FileReaderModule does not use the frame metadata to create the data frame but uses the original size of the file

[kushaljain-apra]

Describe the bug
In the FileReader Module, it does not use frame metadata that we set to create the data frame but instead uses the original size of the file to create the frame. This can be problematic in cases where we need some extra buffer space than the original file's size.

To Reproduce
Steps to reproduce the behavior:

1. Create a frame metadata with explicit frame size like use RawImageFrameMetadata with explicit step size.
2. Send it to external module and check the data size of the frame, it will be the original size of the file instead of the size you would expect after setting the metadata.

Expected behavior
We should be able to set frame metadata to the frame in the FileReader Module.
