Geometry: Delete Geometry

[JackEAllen]

Current Behaviour

If a geometry range is set incorrectly in the Geometry Window such as 0-360 instead of 0-180 degrees, it is not possible to change this after creation.

Being able to edit the geometry is not ideal as there are various ways in which this could be done leading to quite a complicated solution where there would need to be considerations into whether to reassign all angles or just move the last angle when the range is modified.

Instead, it would be more appropriate to be able to delete the newly created geometry and the create a new geometry object to replace the previous one to allow a user to set a new range of angles.

Create a "Delete Geometry" button in the Geometry Window to delete the geometry for a sample stack.

Desired Behaviour

A button exists within the Geometry Window to allow for the deletion of a stacks geometry.

Potential Pitfalls or Risks to Avoid

Ensuring synchronisation of geometry deletion across Mantid Imaging occurs:

• When the geometry is deleted, the main window should remove the angles value associated with a slice in the imageview.
• Reconstruction window geometry values to reset to reflect the deletion of geometry information.

This issue can should not be worked on until completion of #3013
