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.
