### What you've tried already
I tried to install the latest version of mapboxcli using pipx install. This failed
I looked at the sourcecode to find the cause of the failure.
### Expected outcome
`$ pipx install mapboxcli ` should install the mapbox command line tool
### Actual outcome
I got the following error:
```
packaging.requirements.InvalidRequirement: Expected closing RIGHT_PARENTHESIS
python-dateutil (>=2.5.0requests)
```
### Other information
* Version numbers for `mapboxcli` and `mapbox` (from, e.g., `pip list`) : mapboxcli 0.8.0, mapbox 0.16.1
* Operating System : MacOS 13
* Python version number : py39, py310
* How did you install the mapbox cli? Homebrew, pip, other? : pipx
My suggested solution would be to release a new version of mapbox-cli-py to pypi with an upgraded mapbox-sdk-py
The bug (missing comma, resulting in concatenation of 2 dependencies python-dateutil and requests) has been fixed in the 0.18.0 release in this commit:
https://github.com/mapbox/mapbox-sdk-py/commit/f52fa309387584daf96191bc12527ee8e02c83cc
The packaging module has become stricter in checking semantic version numbers, that is why 2.5.0requests is no longer accepted as a valid version string. The requests package is still installed due to the boto3 dependency.
### Proposed solution
Upgrade mapbox dependency to 0.18 in setup.py and make a new release to pypi of mapbox-cli-py.
