Axis Draw Location @ Intercept != 0

[besselfunct]

Description of proposed feature

Option in Axes() to specify new origin:

axes = Axes(
    x_range=[-5, 5, 1],
    y_range=[-2, 2, 1],
    y_axis_config={
        "x_intercept": -2
    },
    x_axis_config={
        "y_intercept": 1
    },
)

How can the new feature be used?

Currently, if plotting raw data with features around the origin, the axes are in the way. Ideally, this should allow for manim animations of raw data to be more tractable.

Additional comments

This issue came up while trying to simultaneously plot traces from .csv files using Axes() defined within a Scene. My clunky workaround will be to shift all of the .csv data manually by some constant amount.

Looking at the source, I believe there might be a way to fix things by modifying manim/mobject/coordinate_systems.py lines 1122-1150, but I'm not familiar enough with the codebase to know if that's correct.

create_axis does seem to be the right place to look, although since it's specific to the Axes mobject, not NumberLine, the change should actually be implemented in Axes itself, not through y/x_axis_config 👍. I'll take a crack at this issue in the coming days
