v0.8.0

Text encoding is now working, all packets assume text input from UTF8 and output to UTF8 as well, colors are untouched and should be parsed by the user, I might add an option to remove them automatically. On the other hand, there is a ColorCode enum and a COLORS array that can be used to parse them (e.g. using RichTextLabel). For more general purposes while using LFSPacket as a serialization tool, add_string_as_utf8 and read_string_as_utf8 can be used to skip encoding conversion.

A bit more testing/fixing should lead to version 1.0, unless I forgot some features.
