Release 0.1

First release of quark, to be matched with go-quark.

A quick note on what this very first release includes:
 * Kprobe & EBPF backends
 * Process aggregation
 * Event flow control
 * Proper documentation
 * 3940 compiled btfhub offsets
 * quark-mon(8) and quark-btf(8)
 * Go bindings

Many thanks to everyone involved, especially: @nicholasberlin, @mjwolf and
@fearful-symmetry.

And there was much rejoicing.
