ts_102221: Add "resume_uicc" command
We've had a "suspend_uicc" command since commit
ec95053249bc7f9308ca1f659d8ef6ac97a6e393 in 2021, but didn't yet
have the corresponding "resume" pair.
Note that you cannot really execute this in a reasonable way from
within pySim, as it is required to power-cycle the card
between SUSPEND and RESUME, see TS 102 221 Section 11.1.22.3.2
