Details

Description:
Version 5.0.0 of python-pylast requires two new runtime dependencies:
* python-importlib-metadata
* python-httpx

For example, without python-httpx, this error is produced by an application that depends on python-pylast:
```
from pylast import WSError, Tag
File "/usr/lib/python3.10/site-packages/pylast/__init__.py", line 37, in <module>
import httpx
ModuleNotFoundError: No module named 'httpx'
```
(Note: this is a partial stack trace)

Any use of this library is impossible without these dependencies.

Additional info:
You can see these dependencies declared here: https://github.com/pylast/pylast/blob/5.0.0/setup.cfg#L35-L36

Additionally, from what I can tell, it does not appear that this lib requires python-six as a runtime dependency. There are no references to python-six in the lib's sourcecode. I believe you should be able to remove this as a required runtime dependency.

Steps to reproduce:
As an example, try installing foobnix from the AUR, which depends on python-pylast. Ensure you do not have one or both of those dependencies installed (I haven't tested python-pylast without python-importlib-metadata installed, as other software I have installed depends on that library). It will fail to start with the above stack trace until you install python-httpx and python-importlib-metadata.

I have the same issue with missing python-httpx. The addition of this dependency can be seen in the upstream changelog here: https://github.com/pylast/pylast/releases/tag/5.0.0

I've had the same issue today after upgrading an app, https://github.com/Taiko2k/TauonMusicBox/issues/750

Traceback (most recent call last):
File "/opt/tauon-music-box/tauon.py", line 248, in <module>
exec(main)
File "/opt/tauon-music-box/t_modules/t_main.py", line 666, in <module>
import pylast
File "/usr/lib/python3.10/site-packages/pylast/__init__.py", line 37, in <module>
import httpx
ModuleNotFoundError: No module named 'httpx'

From what I can tell, this is only for Python versions < 3.8. See [the source](https://github.com/pylast/pylast/blob/5.0.0/src/pylast/__init__.py#L39-L44) for usage and [the configuration](https://github.com/pylast/pylast/blob/5.0.0/setup.cfg#L36) for what I mean. Since Arch is on 3.10 (at the time of this writing), I don't think we need that.

Otherwise, I verified that installing python-httpx solves the issue.
