Description
More specific and actionable version of #263
We frequently convert private keys and other secret values to bytestrings which are subsequently left in memory and could be possibly retrieved. We need cross-platform analog of cryptonite's `ScrubbedBytes` to scrub information from memory on GC. To do that we need following
- [ ] Scrubbed bytes for GHCJS
- [ ] Check whether we can reuse memory type class for GHCJS
- [ ] Expand ByteRepr to work with scrubbed bytes or switch to memory
