[Recommendation] Write as HEX instead of ASCII

This is an Explorer Application for working with MIFARE Ultralight EV1 NFC tags. You can read the complete content of the tag, read and increase the 24-bit counters, protect the data by setting Lock Bits, write data to the free user memory and use a memory protection on base of a 4 bytes long password.

One thing that would be a nice implementation, would be the ability to choose whether you want to;

Write the data as HEX or ASCII: Currently, you have 16 Characters that you can write, and it'll translate that to the Hex Equivalent.

e.g.) If I wanted to write "Learn every day!", starting on Page 4. When translated to HEX it's:

43 65 61 72 6E 20 65 76 65 72 79 20 64 61 79 21

What I think would be nice, is if I wanted to write the HEX directly, for items that do not translate to ASCII in this format.

e.g.) If I wanted to instead write:

0A 04 00 3A 31 01 3F 00 00 00 00 CC 7B 7B BE 0D

I am currently unable to do so, due to lack of ASCII equivalents.
