Cairo 1 support

[piwonskp]

For warp to fully support cairo 1.0 some major changes have to be made:

• [ ] #1066
• [ ] #1075
• [ ] Implement storage
• [ ] Memory to/from calldata
• [ ] Storage to/from calldata
• [ ] Rework Solidity -> cairo type mapping
  • [ ] #1079
• [ ] Builtins (e.g. keccak hash)
• [ ] #1046
• [ ] Add semantic tests
• [ ] #1082
• [ ] Consider removing runtime interaction (deployment etc.). Use some native tool instead
• [ ] Remove cairo1 directory, use package manager instead

Cool ideas:

• [ ] Separate warplib from warp. Create an independent library implementing Solidity types for cairo

Structural changes:

• [ ] #903
• [ ] #849
