improve perf of propEq and propIs

[benji6]

I think defining propEq and propIs in terms of propSatisfies is elegant, but having had problems using these functions on large lists I feel performance is probably more important.

I added a benchmark for propEq and had these results running locally:

# original definition
propEq("value", [1, 2… │ 368,588Hz │ 2.06% error margin

# new definition
propEq("value", [1, 2… │ 438,435Hz │ 1.79% error margin

Could add a benchmark for propIs too but I expect the results would be quite similar.

Let me know what you think
