The implementation was incomplete and lesser than the other backends. No
one ever reported a bug or requested enhancements for this, indicating
that this backend was never used.
Closes#18700
This tool generates a scheme-matching table.
It iterates over a number of different initial and shift values in order
to find the hash algorithm that needs the smallest possible table.
The generated hash function, table and table size then needs to be used
by the url.c:Curl_getn_scheme_handler() function.
