Defines a TokenParser that, in case of an error passed to it, will succeed with the
provided data semantic value.
If it is passed a ParseResult, it will propagate it onwards with no change.
If it is passed a ParseError, it will return the provided data semantic value and
parsing will continue from that point onwards.
It enables error recovery capabilities and defines a synchronisation point at the position where it gets
placed.
Returns
A new TokenParser whose execution will succeed with a valid result or data in case of an error passed to it.
