## What has changed?
I've introduced to the public binding functionality that will compress and decompress public keys of a variety of encoding and key types. This functionality supports all major byte encoding formats and the following EC public key types:
- `secp256k1` pks
- `bls12-381 g1` pks
- `bls12-381 g2` pks
## Why make the change?
We want shorter public (chat) keys and we want to be future proof and encoding agnostic. See the issue here https://github.com/status-im/status-go/issues/1937
---
* Added basic signature for compresspk and uncompresspk
* Added basic encoding information
* make vendor
* formatted imports for the linter
* Reformatted imports hoping linter likes it
* This linter is capricious
* Added check that the secp256k1 key is valid
* Added test for valid key
* Added multiformat/go-varint dep
* Added public key type handling
* Added key decompression with key type handling
* Added handling for '0x' type indentifying
* Added more robust testing
* Less lint for the linting gods
* make vendor for bls12_381
* Added bls12-381 compression tests
* Added decompress key expected results
* Refactor of typed and untyped keys in tests
* Lint god appeasment
* Refactor of sample public keys
* Implemented bls12-381 decompression
* gofmt
* Renamed decode/encode funcs to be more descriptive
* Added binary bindings for key de/compression
* Refactor of func parameters
gomobile is a bit tempermental using raw bytes as a parameter, so I've decided to use string only inputs and outputs
* gofmt
* Added function documentation
* Moved multiformat de/compression into api/multiformat ns
* Moved multiformat de/compression into api/multiformat ns
* Changed compress to serialize on API
