pySim.apdu: Get rid of HexAdapter

Browse Source 
In the past, we always wrapped a HexAdapter around bytes-like data in
order to make sure it's printed as hex-digits.  However, now that we are
doing JSON output it's much easier to let the pySim.utils.JsonEncoder
take care of this in a generic way.

We should do a similar migration all over pySim (pySim-shell,
filesystem, etc.) - but for now only do it in the low-hanging fruit of
pySim-trace aka pySim.apdu
