Add support for interpolated channel

[rodolfocarobene]

I'm adding support for the interpolated channel. This is an easy solution (that should work), but I do not like it much... It is not much clean and does not scale considering the addition of new type of channels (what will I do, continuously add new attributes?). Moreover, it does not solve the problem of having normal readout channels as well as the multiplexed ones. I'm going to think about it a bit more, but in the meantime this is fine.

Checklist before review:

• [ ] Add support in qibolab
• [ ] Test on hardware
• [ ] Documentation is updated.

Checklist before merge:

• [ ] Reviewers confirm new code works as expected.

Hi @JavierSerranoGarcia, this PR should implement support for interpolated channels.

It has to be tested (with the firmware that you are using at TII) accompanied to this qibolab PR: https://github.com/qiboteam/qibolab/pull/863.

Could you please try and report any error you get? Thanks in advance! :-)

[JavierSerranoGarcia]

Thank you @rodolfocarobene , I will test it ASAP

[rodolfocarobene]

Has this been tested or abandoned @JavierSerranoGarcia? If this has not been properly tested I would propose to just close it (keeping the branch) so that we don't have a perpetual stale PR

Hi @rodolfocarobene, I did a quick test and it seemed it works but still not fully tested. Close it and if any problem arises in the future we will open an issue
