style: Add Black formatting exceptions for equations

[uwcdc]

In the source code, there are lengthy equations that, when formatted by Black, may result in less readable or undesired formatting. To address this, we propose introducing #fmt: off and #fmt: on tags to instruct Black to skip formatting for specific lines containing equations.

• Identify the specific lines in the source code that contain equations requiring special formatting consideration
• Introduce #fmt: off (before the lines) and #fmt: on (after the lines) with equations to instruct Black to skip formatting for those lines
• Verify that lines with #fmt: off and #fmt: on tags are excluded from Black formatting
• Ensure that the introduction of formatting exceptions does not compromise the overall readability and consistency of the code
• Update the project documentation to include information about the use of #fmt: off and #fmt: on tags for Black formatting exceptions
