Detailed description

Book issue here: rizinorg/book#91

Extra tests have been added to cover all cases

Removed

• pcA .bytes with instructions in comments removes the dependency on RzCore
• pci C array of bytes with instructions same reason as pcA and was returning same output as pcA
• pcs string useless since ps<cmd> does the same and better.
• pcP python alias for pcp

Moved

• pcv JaVa is now pcJ
• pcz Swift is now pcs
• pcJ javascript is now pcn because the output can be only used on NodeJS.
• pcS bash shellscript is now pcb

Added

• pcg for golang output

Also almost all the outputs (with the exception of ObjC and Vlang) has been tested and validated.

New shell output

Usage: pc[?]   # Print bytes as code byte arrays.
| pc  # Generate a C/C++ byte array.
| pch # Generate a C/C++ 16 bits array.
| pcw # Generate a C/C++ 32 bits array.
| pcd # Generate a C/C++ 64 bits array.
| pca # Generate a byte array in GAS assembly.
| pcb # Generate a bash script with the byte array.
| pcg # Generate a Golang byte array.
| pcJ # Generate a Java byte array.
| pcj # Generate a JSON byte array.
| pck # Generate a Kotlin byte array.
| pcn # Generate a NodeJS buffer.
| pco # Generate a Objective-C/C++ byte array.
| pcp # Generate a Python byte array.
| pcr # Generate a Rust byte array.
| pcs # Generate a Swift byte array.
| pcy # Generate a Yara match pattern.
| pc* # Generate a rizin commands for writing the byte array.

Useful modifiers:
| pch @e:cfg.bigendian=<true|false> # Change endianness for pch, pcw and pcd commands
| pc @! <n>                     # Change the N of bytes (i.e. block size).

Example of usages:
| pch @! 64 @e:cfg.bigendian=true # Generate a C 32 bits array in big endian format, using 64 bytes
| pcp @! 1024                   # Generate a Python byte array of size 1024
| pcj @! 10                     # Generate a JSON bytes array of size 10

LGTM apart from a couple nitpicks.

I would remove all the n_bytes arguments as they just provide a way to replace the blocksize, which can already be done with @!.

Niiice anyway!

i had the same thought, but i wanted to double check with you
