pySim-shell: Add 'decode_hex' command for transparent + linear EF
These commands can be used to decode a user-provided hex-string,
instead of decoding the data read from the file. This is useful
for quickly manually decoding some values read from other locations,
such as e.g. copy+pasted from a eSIM profile in ASN.1 value notation.
