Yara language, hex numbers highlighting

[Jaroslav Nahlik]

I have problems with template for Yara.

using this hex string notation brings question, haw one can highlight those hexa numbers

$s01 = { 4D A8 FF 73 24 A7 3C F6 7A 12 F1 67 AC C1 93 E7 }

Also, there is option use wildcards ??, ?A, A? and elastic spaces [0-10] in those string but that is not a major issue.

Common hex number notation 0x12 i already have recognized an highlighted, thanks to docs for UDL.
