[ixje]

Add post processor arguments and helpers as described in #3 (review) and #3 (comment)

WIP
I can't seem to create a draft PR anymore without paying for a Team license

@meevee98 in you mentioned #3 (comment)

Maybe we can include the simple processors (i.e. bytes to Integer, bytes to str, the default neo default serialization from bytes to array/map) in our package so the user can only import and use them

Do you mean StdLib.serialize and deserialize?

yes, I meant serialize and deserialize from StdLib in that quote

ok thanks. I've added the binary deserialize method as part of the storage module so it's easy to find.
