Add option for automatic subtitle character encoding normalization (#68)

Browse Source 
* Add option for automatic subtitle character encoding normalization

The rationale behind this function is that some services use ISO-8859-1
(latin1) or Windows-1252 (CP-1252) instead of UTF-8 encoding, whether
intentionally or accidentally. Some services even stream subtitles with
malformed/mixed encoding (each segment has a different encoding).

* Remove Subtitle parameter `auto_fix_encoding`

Just always attempt to fix encoding. If the subtitle is neither UTF-8 nor CP-1252, then it should realistically error out instead of producing garbage Subtitle data anyway.

* Move Subtitle encoding fixing code out of if drm tree

* Use chardet as a last ditch effort fixing Subs, or return original data

* Move Subtitle.fix_encoding method to utilities as try_ensure_utf8

* Add Shivelight as a contributor
