Add search-and-replace in rafind2

[trufae]

Right now its only possible to do this from r2, will be good to have an option in rafind2 to do the same with a rafind2 oneliner.

Hi @trufae, Can you give me some more idea on this. I will try to solve this if possible.

TIA, Kushal

Hey @iamkkushal sorry for the late reply. rafind2 is not linking to RCore, so i can think of two solutions:

1) construct an r2 oneliner that does the search+replace like r2 -c 'w hello @@/ world' file 2) implement the thing using the r_io api, which is prefered but more tedious but its not difficult.

The most difficult part of this requires deciding which getopt flags to use to handle this operation. The new flags should do this:

• New string to write (hex, ascii, wide string..)
• insert or replace (resize the file or keep it the same size and warn if new string is longer than original)
