installation error - `pip install vtk==9.1.0`

[jgunstone]

in the requirements.txt file vtk is pinned to 9.1.0 https://github.com/ladybug-tools/honeybee-vtk/blob/230165aa8003717a91b5c71bfa68ca2c0655786b/requirements.txt#L2

I'm getting an error when doing

pip install honeybee-vtk

resulting from:

(hbtests) jovyan@PORT4028:/mnt/c/engDev/git_mf$ pip install vtk==9.1.0
ERROR: Could not find a version that satisfies the requirement vtk==9.1.0 (from versions: 9.2.4, 9.2.5)
ERROR: No matching distribution found for vtk==9.1.0

i.e. looks like 9.1.0 is no longer available (despite being here: https://pypi.org/project/vtk/9.1.0/)

many thanks,
