parser.d references non-existant method `std.uni.unicode.parseSet`

[RomanHargrave]

At line 35 of pry/grammar/parser.d, unicode.parseSet is called.

This does not appear to exist in phobos, nor is it defined in Pry.

The pull that adds it to phobos. I thought it would take a week or two to merge it but it failed for months with some link-time error.

For now you could just merge it locally.

I'll do my best to get it merge now that it passes auto-tester.

Grammar mode is removed so can't be an issue anymore.
