The code generated by the generator now also writes the files
on_response(...) method. Also, all the generated files are
saved in a dictionary containing `constructorId: class`
The code generated by the generator now classifies the output files
in their corresponding categories, also writing their __init__(...)
with documented arguments, and the on_send(...) method
A TLObject class has been added, as well as a method for tokenizen .tl files.
A TLObject can be created by simply calling `TLObject.from_tl(tl_line)`,
this will tokenize the .tl line and return a new TLObject with all
the required properties extracted.
Also added another method to load .tl files and yield TLObjects, including
a SourceBuilder that can be later used to generate Python code.
The initial release contains the most basic implementation of TLSharp core.
This is also fully untested, since no test can be done until more work is done.
