Implement Python 3 bindings, so wasm3 can be easily used from Python.

I just found https://github.com/dalance/svlint and would be interested how it copes with the ibex code base.

This is discussed a bit more in #456.

Currently, to copy off files from the fs is to 1. mount, 2. chattr, 3. chmod/chown, 4. copy files off. However, this is destructive to the fs (since it changes permissions/users). Instead, there should be a less invasive way to copy off files that doesn't mess with the underlying fs so that people can copy the fs and use it somewhere else.

I have found a bug in the memory dump. The size of the disassembled code is not enough for the instruction addi X28, X28, 0x28. The dump generated is:

0x00000078 0x028e0e13 addi x28,x28,0x000000254 addi x28, x28, 0x28

And as it can be seen the 8 of the immediate is truncated by the line number.

I think the fix is easy: in file rars/src/rars/riscv/dump/SegmentWindowDumpFormat.java cha
