[FEAT] Add support for Vyper contracts

[thevaizman]

Description

Support for Vyper compiled contracts.

Spec

We currently only have one supported compiler - solc.
That means that whenever a contract is analyzed, we only look for patterns that are used in solc in order to extract the storage layout information.
That means that we only minimally support Vyper contracts as only the patterns that are shared between the two compilers will get picked up by our analysis.

We should be able to identify that a contract was compiled by Vyper, either by looking for distinctive bytecode patterns, or by looking for the distinctive Vyper signature (available only on modern Vyper compiler versions) or even by providing a flag with the compiler type.

Then we should add support for the currently missing bytecode patterns rhat are generated by Vyper compiler to perform storage related operations (e.g., mapping accesses).
