This and a few other failing fuzzing tests were due to incorrectly
parsing numerics from strings. Some of our casting was done properly,
but it wasn't being applied to all cases where the behavior was needed.
It was also attempting to parse a string[0..N] N times until
`string[0..N].parse()` would no longer succeed. This searches for the
index of the first illegal character and parses the resulting slice
once.
Tests were added for some of the edgecases that were previously failing.
This PR also adds a macro in vdbe/insn.rs that allows for a bit of
cleanup and reduces some matching.
Closes#1053
