Refactor Channel on top of sunkit_instruments.response.abstractions.AbstractChannel

[wtbarnes]

This is a first attempt at refactoring the Channel class on top of the AbstractChannel class from sunkit-instruments. The latter is still in the form of a draft PR sunpy/sunkit-instruments#98 so this is an experimental PR at this stage.

The goal here is to easily enable calculating the temperature response functions.

As it stands, this represents a breaking change to the Channel API.

ToDos before this can be merged:

• Merge Add a topic guide for response function vocabulary sunpy/sunkit-instruments#111
• Merge Add abstract base class for channels sunpy/sunkit-instruments#98
• sunkit-instruments release including AbstractChannel
• Fix tests
• Refactor tests (?)
• Fix gallery example
• Breaking changelog (deprecation will be very difficult)
• Review all docstrings
• Run IDL comparison tests to ensure consistency

Summary by Sourcery

Refactor the Channel class to extend AbstractChannel, enhancing the API with additional parameters and methods for more flexible and accurate temperature response function calculations. This change introduces a breaking change to the Channel API.

Enhancements:

• Refactor the Channel class to inherit from AbstractChannel, introducing a more structured approach to handling channel properties and response functions.
• Add new parameters to the Channel class constructor, including include_eve_correction, include_crosstalk, correction_table, and calibration_version, to enhance flexibility in response function calculations.
• Rename several properties for clarity, such as primary_reflectance to primary_mirror_reflectance and focal_plane_filter_efficiency to focal_plane_filter_transmittance.
• Introduce new methods and properties to handle complex calculations like mirror_reflectance, filter_transmittance, and energy_per_electron.
