Distribute pioasm as a package/executable #1345
Description
It would be very convenient to have pioasm distributed as a package, in addition to the current state where it's distributed as source code that should be compiled as part of the project. This was mentioned in #396 but that issue seemed to drift to other areas.
By "package" I mean a standalone application that can be installed with the user's package manager, e.g. apt install pioasm.
Other options are a downloadable executable, or even a python wrap that could be installed with pip install pioasm.
Context: I'm porting the PIO to Zephyr, which does not use pico-sdk's build system. We would prefer to have pioasm installed once as part of the installation process, rather than building it as part of the main build.
