Wrap word support ansi

[nam-hle]

This PR supports ANSI word wrapping (#11). Here is my solution:

• Apply our logic on an ANSI-stripped string to get strings' lengths and offset to the next string (because of trim)
• Then use that information to slice real string

TODO: Find out the way to split ANSI strings by newline character in wrapCell.ts
