feature_request(sequences): font effects support

[Kristinita]

1. Summary

It would be nice, if SublimeANSI will support font effects (see Font Effects section) as bold, underline and reverse.

2. Argumentation

More features in output. For example, I use bold and underline text in output of my programs.

3. Environment

• Windows 10 Enterprise LTSB 64-bit EN,
• Sublime Text Version 3.1.1, Build 3176 Portable,
• Python 3.7.0,
• ANSIEscape 0.2.5,
• SublimeREPL 2017.01.28.19.13.15.

4. Steps to reproduce

I open SublimeREPL Python Interpreter → I paste this code:

print(u"\u001b[1m SashaBold \u001b[0m\u001b[4m SashaUnderline \u001b[0m\u001b[7m SashaReversed \u001b[0m")

→ Enter.
