This updates the tables.rs file to be compatible with the latest
available unicode standard, allowing for new glyphs like the yawning
face to be recognized properly.
The unicode.py script has also been updated to python3, since that
should be supported on more systems.
This diff adds benchmarks to get more info regarding Issue #1.
It appears that the remaining difference between the "simple"
case and the "cargo" case is the result of a difference in
performance between using `match` and `if` for tight loops.
I suspect it's because of the way that match arms get reordered:
if I manually reorder the "if" statement, I can reproduce the
match performance.
Also added a couple #[inline] annotations in tables.rs, though
the difference in performance in my measurements is negligible.
Bumped version number to 0.1.1.
