This PR improves the instantiation speed of MimeType by parsing the MimeParams lazily.

MimeParams accepts now a string of the parameter rest.

Be aware that when doing many comparisons the risk of a false-positive result increases.
In this case, there are 10 comparisons, you can thus expect the following amount of false-positive results:
  0.50 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.10 false positives, when considering a   1% risk acceptance (**, ***),
  0.01 false positives, when considering a 0.1% risk acceptance (***)

Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case, there are 17 comparisons, you can thus
expect the following amount of false-positive results:
  0.85 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.17 false positives, when considering a   1% risk acceptance (**, ***),
  0.02 false positives, when considering a 0.1% risk acceptance (***)

@Uzlopak Can you reduce the number of iterations on the benchmarks? The current benchmark ci is taking many hours.

The benchmark has taken 16 hours to complete, which is an improvement over the 17 hours it took the first time, but a relatively small one if you ask me. I wonder what's taking so long, it would be beneficial to lower that time further.

@aduh95
I guess it is because I also benchmark for toASCIILower. Because in main toAsciiLower is not exported, it throws errors, which are collected. So that is super slow.

Ah yeah, the to-ascii-lower benchmark ran for 9 hours, that's probably it indeed.
