Feature Request: RF Range Scanning/Receive

[ResistanceIsUseless]

Hi @joelsernamoreno I know you are in the middle of adding a bunch of functionality right now, so I wanted to propose some enhancements.

It would be nice if you could setup the ECRF to scan a frequency range and save the requests to SD as capture files. Similar to what the FlipperZero does with hopping and saving known or raw captures. Having two CC1101's gives the ECRF a slight advantage so you could have them covering different frequency ranges.
