match: provide and use a quick way to escape a single byte

The previous function has a lot of overhead (including being a function). In
the `_globre` case, we always escape a single byte. So we provide a dictionary
dedicated to this use case. We directly use the dictionary to avoid a function
call, these are expensive in Python.

Again, this raise a very significant performance gain:

Before: ! wall 0.059793 comb 0.060000 user 0.060000 sys 0.000000 (median of 100)
After:  ! wall 0.020390 comb 0.020000 user 0.020000 sys 0.000000 (median of 146)

Total improvement for the full series:

Before: ! wall 0.153153 comb 0.150000 user 0.150000 sys 0.000000 (median of 66)
After:  ! wall 0.020390 comb 0.020000 user 0.020000 sys 0.000000 (median of 146)
