Hello hackers,

Here's the progress I've made in coverage for testing Bitmapset.

coverage: HEAD v1 v2
lines......: 87.1 87.7 91.3
functions..: 100 100 100
branches...: 63.5 66.5 77.9

I've also added a function that performs a variety of operations using
random data.

For reference radixtree has:

coverage: HEAD
lines......: 98.3
functions..: 97.2
branches...: 89.4

best,
