Support for HID iClass (Picopass files)

[lilgangus]

Added in basic HID iClass key support for quac based on picopass flipper zero application.
Note: I did not like having a finite duration that the key emulation lasts for, so I have it emulating the key until the user selects to back out.

Thanks for the contribution! Thinking about how this would integrate with playlists (.qpl) if the only way to play them is with a manual stop. Perhaps we can tweak this so that it supports both? That is, some settings that specify:

• Picopass Tx: Manual / Auto
• Picopass Tx default duration: X sec

Then, in a Playlist file, we can specify the signal name and a following optional parameter (similar to SubGhz, RFID, and NFC) which determines their Tx interval. And for Picopass, we can have:

• <nothing> // uses the default time interval in the settings
• X // transmits for X ms
• manual // transmits until user input

Also, we'll want the picopass icon for Importing.

What do you think?
