📌 Pin maximum python version to <4.0

[weiji14]

Relax the hard upper Python version pin so that Python 3.12+ can be used. Done by bumping scipy from 1.9.0 to 1.9.2 in the lockfile. Still need to set python <4.0 as required by stackstac.

Note that original python <3.12 pin was done in d88fd83/#34.

Full stacktrace if trying to remove upper Python version pin completely and running poetry lock --no-update:

The current project's Python requirement (>=3.8) is not compatible with some of the required packages Python requirement:
  - stackstac requires Python >=3.8,<4.0, so it will not be satisfied for Python >=4.0
  - stackstac requires Python >=3.8,<4.0, so it will not be satisfied for Python >=4.0
  - stackstac requires Python >=3.8,<4.0, so it will not be satisfied for Python >=4.0
  - stackstac requires Python >=3.8,<4.0, so it will not be satisfied for Python >=4.0

Because no versions of stackstac match >0.4.0,<0.4.1 || >0.4.1,<0.4.2 || >0.4.2,<0.4.3 || >0.4.3
 and stackstac (0.4.0) requires Python >=3.8,<4.0, stackstac is forbidden.
And because stackstac (0.4.1) requires Python >=3.8,<4.0
 and stackstac (0.4.2) requires Python >=3.8,<4.0, stackstac is forbidden.
So, because stackstac (0.4.3) requires Python >=3.8,<4.0
 and zen3geo depends on stackstac (>=0.4.0), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For stackstac, a possible solution would be to set the `python` property to ">=3.8,<4.0"
    For stackstac, a possible solution would be to set the `python` property to ">=3.8,<4.0"
    For stackstac, a possible solution would be to set the `python` property to ">=3.8,<4.0"
    For stackstac, a possible solution would be to set the `python` property to ">=3.8,<4.0"
