v0.3.0 Venice (#1319)

The parser and semantic analysis stage of Solang have gone through
[a security audit](https://github.com/solana-labs/security-audits/blob/master/solang/Trail_of_Bits_Solang_Final_report.pdf). All security issues have been fixed.

### Added
- The CLI now has a `--release` option, which disables printing of errors [salaheldinsoliman](https://github.com/salaheldinsoliman)
- **Substrate**: chain extensions can be now used.
  [xermicus](https://github.com/xermicus)

### Fixed
- Solidity error definitions are now parsed.
  [seanyoung](https://github.com/seanyoung)
- The Ethereum Solidity parser and semantic analysis tests are now run on Solang sema during
  `cargo test`.
  [seanyoung](https://github.com/seanyoung)
- If a function returns a `storage` reference, then not returning a value explicitly is an error, since
  the reference must refer to an existing storage variable.
  [seanyoung](https://github.com/seanyoung)
- Many small improvements have been made to the parser and semantic analysis, improving compatibility
  with Ethereum Solidity.
  [seanyoung](https://github.com/seanyoung)
  [xermicus](https://github.com/xermicus)
  [LucasSte](https://github.com/LucasSte)

### Changed
- **Solana**: Addresses are now base58 encoded when formated with `"address:{}".format(address)`.
  [LucasSte](https://github.com/LucasSte)
- **Substrate**: No longer use the prefixed names for seal runtime API calls, which grants small improvements in contract sizes. [xermicus](https://github.com/xermicus)
