Tab support for ChordPro parsing: PeggySyntaxError: Expected "#", "%", "[", "\\", "]", "{", "|", or "}" but "3" found.

[AdrienAnelli]

When there is a tab part inside a chord pro format like:

E|--------------------------|-x--5-|-------------------------|-x--3-|
B|--------------------------|-x--5-|-------------------------|-x--3-|
G|--------------------------|-x--5-|-------------------------|-x--4-|
D|--------------------------|-x--5-|-------------------------|-x--3-|
A|------5-------------------|-x--7-|-------5-----------------|-x--5-|
E|--5/7----7--5--3--0--3/5--|-x--5-|--5/7------7--5/3--0--3--|-x--3-|

E|--------------------------|-x--5-|-------------------------|-x--3-|
B|--------------------------|-x--5-|-------------------------|-x--3-|
G|--------------------------|-x--5-|-------------------------|-x--4-|
D|--------------------------|-x--5-|-------------------------|-x--3-|
A|-------5--7--5------------|-x--7-|-------5-----------------|-x--5-|
E|--5/7-----------7--0--5---|-x--5-|--5/7------7--5\3--0--3--|-x--3-|

The chord pro format cannot be parsed and this error is thrown: PeggySyntaxError: Expected "#", "%", "[", "\\", "]", "{", "|", or "}" but "3" found.

Also, this same tab description entered as text (chords over words) will be converted to chord pro format as:

This was working fine with ChordSheetParser

@AdrienAnelli Thanks for reaching out and submitting your issue.

For the first problem I have good news: I've been working on proper abc/grid/ly/tab section support for the ChordProParser, and I'll probably release that within a couple of days: #1144

The second problem is a bit harder to solve. ChordsOverWordsFormatter is not designed (yet) to recognise tab sections and treat them differently from chords with lyrics. I'll put this issue on the board though and see when I can invest some time to try and get this working.
