Add 'path' option to ImagePrompt data_format

[gfinol]

Purpose

This PR adds the "path" option to data_format in ImagePrompt for the prithvi_io_processor plugin.

Notice that the plugin already supports that option, but fails when used with a file because of the pydantic check.

Code Review

This pull request adds the path option for data_format in the ImagePrompt model, allowing local file paths to be used as image inputs for the prithvi_io_processor plugin. The change itself is correct, but it lacks corresponding tests to validate the new functionality. Additionally, I've identified a pre-existing issue with the bytes data format option on the same line, which appears to be non-functional. I've added comments with suggestions to address both points to improve the robustness and correctness of the plugin.

While this change correctly adds the path option to data_format, the new functionality is not covered by any tests. To ensure correctness and prevent future regressions, please add a test case for data_format: "path" in tests/plugins_tests/test_io_processor_plugins.py. You could add a new test function or parameterize an existing one to handle the path case, for example by downloading the test image to a temporary file and passing its path.

[gemini-code-assist]

The "bytes" option in data_format appears to be non-functional. The load_image function in prithvi_processor.py expects a list of strings, but for data_format="bytes" it would receive a list containing a bytes object. The logic to handle bytes data within load_image is commented out, and read_geotiff is not called correctly for this case. This will lead to a runtime error. Since you are modifying this line, it would be beneficial to either fix the implementation for "bytes" or remove it from the Literal to avoid confusion.
