Hyperion testing 28/11

Did some brief testing of #685 on the beamline. Found some minor issues:

Error of:

ERROR:root:device `array_data` raised unexpected exception TypeError

TypeError: BL03I-DI-OAV-01:PVA:ARRAY with inferred datatype ndarray from typeid='epics:nt/NTNDArray:1.0' specifier='U' cannot be coerced to Array1D[np.uint8]

Fixed by changing the type to np.ndarray.

The docs at https://diamondlightsource.github.io/mx-bluesky/main/developer/general/how-to/deploy-a-release.html say to pip install dodal after mx_bluesky this ends up with the dodal from pypi, not the local one as:

1. Pip installing mx_bluesky installs the pypi version
2. If you try and pip install the local version pip recognises that you have the one from pypi and just says there's no need to install anything new

• The pip fix was rejected in Clean up order of deploying #693
• OAV PinTipDetection fix merged in Fix type of array from beamline testing dodal#937
