[gmem-sharp] - C# port/bindings

[otvv]

Everything seems to work as intended for a first interaction. This will keep receiving updates

This won't be merged into main. (I want to separate gmem's branches at a some point and make the main branch act as a "repository" of sorts, with directions of all gmem's versions and/or ports.

TODO:

• Make a new README for this branch
• Improve building system (create a building script) and add instructions in the README.
  (.NET Core on Linux can be a little wonky. Specially the building process.)
• Improve the code, add an error/exception handler.
• New functionalities (pattern scanning, code execution, etc)
  (All new functionalities will be implemented first on the C++ version then they will be implemented on the other versions)
