`ota.status.status()` missing support for `nfs_keys` subtype

[hasanen]

Hey

started to test this library as it looks useful and perfect for our use case.

In our partition table we have partition with subtype nvs_keys and this makes ``ota.status.status()` break

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "ota/status.py", line 138, in status
  File "ota/status.py", line 84, in partition_table_print
KeyError: 4

I did some testing at it seems that changing following

micropython-esp32-ota/mip/ota/status.py

Line 75 in 3c87b42

{0: "ota", 1: "phy", 2: "nvs", 129: "fat"}, # DATA subtypes

to

{0: "ota", 1: "phy", 2: "nvs", 4: "nvs_keys", 129: "fat"},

Solves the issue.

I can do PR, but I'm not sure what is the build process of building corresponding .mpy file.

From the micropython directory, you should be able to use this command (replacing FILENAME with the python file you would like to convert)

./tools/mpy-tool.py -f FILENAME

Let me know if that works!

Sorry for the slow response on this issue. I've been on holiday for the last 3 weeks. Your fix looks good, though it was not intended that the app crash on unidentified partition types. I'll fix that as well and post an update.
