Refactor makesyscalls.lua into a library

• main.lua replicates the functionality of makesyscalls.lua
• Individual files are generated by their associated module
  • Modules can be called as standalone scripts to generate a specific file
• Data and procedures are performed by objects instead of procedual code
• Bitmasks are replaced by declarative types
• Temporary files are no longer produced, writing is stored in memory
• Comments provide explanation to functions and semantics
