Excluded directories are still parsed #2
Description
When directories are passed in the -e flag, the expectation is that all namespaces under this will be ignored in the computation. However, to do so, all the files in this dirs are parsed (to convert the filename to a namespace that should be excluded from dependency graphs).
Due to this, the reader fails even when the user expects it will never parse the directory. For example: the error in #1 will be reproduced even if an explicit -e flag is passed to exclude code containing tagged literals.
There needs to be a better way to handle this, where the files are completely ignored without requiring namespace parsing.
