Various mod fixes (#95)
* Terminate offline mod recompilation if any functions fail to recompile

* Fixed edge case with switch case jump table detection when lo16 immediate is exactly 0

* Prevent emitting duplicate reference symbol defines in offline mod recompilation

* Fix function calls and add missing runtime function pointers in offline mod recompiler

Modding Support PR 1 (Instruction tables, modding support, mod symbol format, library conversion) (#89)
* Initial implementation of binary operation table

* Initial implementation of unary operation table

* More binary op types, moved binary expression string generation into separate function

* Added and implemented conditional branch instruction table

* Fixed likely swap on bgezal, fixed extra indent branch close and missing
indent on branch statement

* Add operands for other uses of float registers

* Added CHECK_FR generation to binary operation processing, moved float comparison instructions to binary op table

* Finished moving float arithmetic instructions to operation tables

* Added store instruction operation table

* Created Generator interface, separated operation types and tables and C generation code into new files

* Fix mov.d using the wrong input operand

* Move recompiler core logic into a core library and make the existing CLI consume the core library

* Removed unnecessary config input to recompilation functions

* Moved parts of recomp_port.h into new internal headers in src folder

* Changed recomp port naming to N64Recomp

* Remove some unused code and document which Context fields are actually required for recompilation

* Implement mod symbol parsing

* Restructure mod symbols to make replacements global instead of per-section

* Refactor elf parsing into static Context method for reusability

* Move elf parsing into a separate library

* WIP elf to mod tool, currently working without relocations or API exports/imports

* Make mod tool emit relocs and patch binary for non-relocatable symbol references as needed

* Implemented writing import and exports in the mod tool

* Add dependencies to the mod symbol format, finish exporting and importing of mod symbols

* Add first pass offline mod recompiler (generates C from mods that can be compiled and linked into a dynamic library)

* Add strict mode and ability to generate exports for normal recompilation (for patches)

* Move mod context fields into base context, move import symbols into separate vector, misc cleanup

* Some cleanup by making some Context members private

* Add events (from dependencies and exported) and callbacks to the mod symbol format and add support to them in elf parsing

* Add runtime-driven fields to offline mod recompiler, fix event symbol relocs using the wrong section in the mod tool

* Move file header writing outside of function recompilation

* Allow cross-section relocations, encode exact target section in mod relocations, add way to tag reference symbol relocations

* Add local symbol addresses array to offline mod recompiler output and rename original one to reference section addresses

* Add more comments to the offline mod recompiler's output

* Fix handling of section load addresses to match objcopy behavior, added event parsing to dependency tomls, minor cleanup

* Fixed incorrect size used for finding section segments

* Add missing includes for libstdc++

* Rework callbacks and imports to use the section name for identifying the dependency instead of relying on per-dependency tomls
