Update list of new and unsupported functions

This patch updates the list of unsupported functions in the README and
the TODO and the list of functions changed in the libnitrokey 3.5
release:

- List all `*_as_string` functions as unsupported.
- List deprecated functions as unsupported.
- List `NK_read_HOTP_slot` as unsupported until an equivalent function
  for TOTP exists.
- Ignore the changes to `NK_get_progress_bar_value` as the function is
  not yet used by `nitrokey-rs`.
- Add the new functions from version 3.5 to the list of missing
  functions.
