Commit Message

CRLF parsing micro-optimization

This is a tiny optimization on how CRLFs are checked
(`String.ends_with?` is faster than a regex), which speeds up the
stream processing process by a few percentage points.

There are of course bigger fish to fry than this.  E.g. it shouldn’t
make a huge difference but I wanted to do a quick example of the sort
of profiling/changes that should be possible now to encourage people to
look for optimization opportunities.

Before:
#process stream - single chunk:     100000   17.98 µs/op
#process stream - multi chunk:       50000   39.90 µs/op

After:
#process stream - single chunk:     100000   16.70 µs/op
#process stream - multi chunk:       50000   35.78 µs/op
