Optimize hex parsing. (#520) * Optimize hex parsing. The biggest improvement comes from using a `const` string as table. That avoids (potentially) a lazy initialization check on accessing the `_charFlags`. Also, a constant string may have a fixed location in memory. Negating the "is valid hex" and putting the bit in bit 7 allows using `entry.toSigned(8)`, which a smart compiler should be able to turn into a single sign-extending opcode. (Using `(entry & 0x0F) - (entry & 0x80)` works too.) The `missing_whitespace_between_adjacent_strings` lint doesn't understand that not all strings are text. Maybe it shouldn't trigger for strings containing character escapes.
