avoid finalizer, may destabilize the GC (#28) 
forgot about https://github.com/nim-lang/Nim/issues/4851 when writing it

use external rng instead of nimcrypto (#23) 
* use external rng instead of nimcrypto

allows passing in different RNG's to generate keys

* pass in array of random data to random keygen function

* back to a proc

* docs

* gcsafe rng callback needed

* introduce foolproofrng that can't fail

* silence compiler warning

* hint at random not being good enough in defect

use requiredInit (#22) 
* use requiredInit

Use requiredInit on keys - this simplifies error handling by providing
more compile-time guarantees through type.

Loophole: `clear` will leave an invalid key type in memory, not
guaranteed by type - it requires an explicit action to produce, so it's
somewhat better than the current situation where by default, keys are
invalid, but it's not watertight.

something like a `sink` would be needed which would have to guarantee
that `clear` is the last use of the instance.

* close requiresinit loophole

* remove clear for public stuff

* fix side effects

`secp256k1_context_no_precomp` is constant actually

* document nosideeffect

* document nosideeffect

* document fix
