[wishlist] hex-grep utility to search for the string or pattern in the hex file

[Alexander Belchenko]

Sometimes it could be useful to search in the hex file content for the string or the pattern, i.e.

python hex-grep [OPTIONS] PATTERN HEX_FILE...

Possible options:

-i - ignore the case
-F - pattern is the substring to look for, not the regular expression.
--hex - pattern is the chain of hex bytes to look for, e.g. python hex-grep --hex "2A FF 3C" foo.hex

For matches found we can just print name of the file and offset. Maybe provide a little context as hex dump.
