Feature/pix2deg-offset

[OmerShubi]

Description

Fixes #534 - Adding center_offset to center_origin function and propagating it to pix2deg.

Implemented changes

The offset is implemented in the center_origin() function in pymovements.gaze.transforms.

The offset should be given in centimeters and is expected to be a tuple of floats with a zero default (center_offset: tuple[float, float] = (0, 0)). A positive value moves the origin to the left and down respectively.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change is or requires a documentation update

How Has This Been Tested?

Please describe the tests that you ran to verify your changes.
Provide instructions so we can reproduce.
Please also list any relevant details for your test configuration

• test offset in tests/unit/gaze/transforms/center_origin_test.py
• test offset in tests/unit/gaze/transforms/pix2deg_test.py
• test offset in tests/unit/gaze/gaze_transform_test.py

In all cases two additional tests where created, one where the origin is top left and the other center. An offset of (10,10) is applied.
