mip: Dependency of copy not installed

[sandyscott]

When I installed the copy package via mip (on attached host PC, not running on the device), the dependecy types was not installed.

To Reproduce:

Raspberry Pi Pico running v1.20.0
PC running Python 3.10, pip 3.10, mpremote 1.20.0

$ mpremote connect com14 mip install copy
Install copy
Installing copy (latest) from https://micropython.org/pi/v2 to /lib
Installing: /lib/copy.mpy
Done
$ mpremote repl
Connected to MicroPython at COM14
Use Ctrl-] or Ctrl-x to exit this shell
>>> import copy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "copy.py", line 51, in <module>
ImportError: no module named 'types'
>>>

Thanks for the report, it seems the dependency on types hasn't been declared in the manifest https://github.com/micropython/micropython-lib/blob/master/python-stdlib/copy/manifest.py

These manifests were automatically generated from the earlier setup.py based installer system which was pretty inconsistent in quality, so it's not surprising that some things like this have been missed

It sounds like you've found the root cause of that issue, but there's also a problem with the types package:
(I wrote this comment almost immediately after posting the issue, but for some reason hadn't submitted it)

$ mpremote connect com14 mip install types
Install types
Installing types (latest) from https://micropython.org/pi/v2 to /lib
Package may be partially installed
mpremote: Package not found: https://micropython.org/pi/v2/package/6/types/latest.json

Yes I added an extra comment to this PR referring to a proposed fix to the types package I submitted previously in PR #646
