Expose and performance optimize validation

[blakeembrey]

Optimize the validation functions. It's a good amount more code, but now that we're on ESM if format isn't used it can be dropped from the output of the package size. Added size-limit to check the overall bundle size too.

Perf before (using format as the proxy):

 ✓ src/index.bench.ts > format 5086ms
     name                                      hz     min     max    mean     p75     p99    p995    p999     rme  samples
   · basic                          16,270,663.28  0.0000  0.1058  0.0001  0.0001  0.0001  0.0001  0.0002  ±0.12%  8135332
   · simple parameters               2,482,510.90  0.0003  0.2038  0.0004  0.0004  0.0005  0.0005  0.0010  ±0.15%  1241256
   · quoted and escaped parameters   1,686,373.42  0.0005  0.2309  0.0006  0.0006  0.0007  0.0007  0.0012  ±0.24%   843187

After:

 ✓ src/index.bench.ts > format 5878ms
     name                                      hz     min     max    mean     p75     p99    p995    p999     rme   samples
   · basic                          20,233,039.07  0.0000  0.1885  0.0000  0.0000  0.0001  0.0001  0.0002  ±0.12%  10116520
   · simple parameters               3,574,345.35  0.0002  0.4722  0.0003  0.0003  0.0004  0.0004  0.0009  ±0.26%   1787173
   · quoted and escaped parameters   3,094,882.46  0.0002  0.3335  0.0003  0.0003  0.0004  0.0005  0.0009  ±0.51%   1547442

Reasonably significant and worth the trade-off IMO.

LGTM!

I left a comment but just saw that the parse()function also does not validate if the input is a string and only fails in skipOWS().
