Impossible to install package because of Cython 3 and PyYaml > 5.4.1 incompatibility

[sbr-dev]

Hello,

As it has been heavily documented on github, Cython 3 broke PyYaml > 5.4.1 installation. See yaml/pyyaml#724

Because of this major bug, it is now impossible to install digital-ocean-spaces with pip.
I suggest to modify the requirements.txt to force the PyYaml version to 5.3.1.

As a quick fix:

• Copy the requirements.txt
• Modify the version of PyYaml to 5.3.1
• install all with pip install -r requirements.txt
• then install the package with pip install --no-deps digital-ocean-spaces

Cheers
