Version 0.11

[rumbledethumps]

This release has some deep changes. The release notes:
https://github.com/picocomputer/rp6502/releases/tag/v0.11

In addition...

The build tools in vscode-cc65 and vscode-llvm-mos were improved. You can now launch programs with the usual F5 instead of CTRL-SHIFT-B.  It's also possible for the linker to pass all three vectors (nmi, reset, and irq) to the rp6502.py tool. You'll need to manually merge these changes into your project if you want them.

The llvm-mos project added stdio to their standard library. I updated the sdk so now you can do the usual fopen things. It's basically the same structure as cc65 with different constants, which is annoying but still easy to maintain. Go click the thumbs up on the pull request: llvm-mos/llvm-mos-sdk#395
