Refactor: Amf3 implementation (#998)

Browse Source 
* Update AMFDeserializeTests.cpp

Redo Amf3 functionality

Overhaul the whole thing due to it being outdated and clunky to use

Sometimes you want to keep the value

Update AMFDeserializeTests.cpp

* Fix enum and constructors

Correct enum to a class and simplify names.
Add a proper default constructor

* Update MasterServer.cpp

* Fix bugs and add more tests

* Refactor: AMF with templates in mind

- Remove hard coded bodge
- Use templates and generics to allow for much looser typing and strengthened implementation
- Move code into header only implementation for portability

Refactor: Convert AMF implementation to templates

- Rip out previous implementation
- Remove all extraneous terminology
- Add proper overloads for all types of inserts
- Fix up tests and codebase

* Fix compiler errors

* Check for null first

* Add specialization for const char*

* Update tests for new template specialization

* Switch BitStream to use references

* Rename files

* Check enum bounds on deserialize

I did this on a phone
