Release v6.1.0

This release adds:

• The dynamic linker which, paired with wasixcc,
  can load DL modules at runtime
• New WASIX syscalls for reflection, dynamic function invocation and closure creation;
  this makes WASIX compatible with libffi
• Better support for the Exception Handling proposal in the LLVM backend
• The --build-remote flag for wasmer deploy, which lets you build packages in the
  cloud rather than locally
• And many more stability fixes and improvements.
