Automatically set correct compiler version when instantiating Slither

[Yustynn]

Describe the desired feature

I'd like the version to be auto-detected (e.g. from the solidity pragma) and set. Maybe I'm doing it wrong, but currently I had to write non-slither code to do this for me.

Use case: I'm doing analysis on many contracts of different compiler versions.

Is this feature desirable? Idm making a PR if yes, would appreciate any guidance on implementation if you have preferences

Hi! crytic-compile already offers this functionality of "guessing" the solc version. You need to list the allowed and installed versions in the solc_solcs_select option / --solc-solcs-select flag when running Slither or crytic-compile.

https://github.com/crytic/crytic-compile/blob/20df04f37af723eaa7fa56dc2c80169776f3bc4d/crytic_compile/platform/solc.py#L713-L733

Additionally, if you're pulling code from Etherscan, we'll fetch the version number that was used for verification there so there's no need to be guessing.

Ah that's great, thanks :)
