Include into r2

[trufae]

I was checking the code of your plugin, and there are few things that must be changed to be included into r2:

• replace sdb logic to just be an array of structs in C
• fix few syntax things to match r2 coding style
• write an rbin plugin that tells the user to use uf2:// instead.. or maybe we can make rbin redirect to a different io plugin on demand. fs plugins already do a similar thing and i think it can be doable, also for other plugins like the dyldcache

uf2 is quite common fileformat and i think it will be good to ship it

Initial poc for the bin redirector

feel free to improve the implementation and send a pr to add the uf2 io plugin in r2 too

good work!
