SDK v16.0.0

Breaking changes

• __from_ascii and __to_ascii now take a void pointer to a context object and pass it though to the read/write callback. This is a trick from dl_iterate_phdr to allow passing general lambdas that refer to an ambient context.

New features

• Port fwrite from PDCLib; port cc65 file writing backend (write) for commodore
  • Known issue: Doesn't yet support ASCII->PETSCII translation in text mode; outputs as if opened in binary mode

Bug fixes

• #331 - [Mega65] Fix C++ static assert in ethernet controller - @mlund
