Internal function to verify file paths and format
i_verify_path_and_format(
path,
format = NULL,
exclude_if_matches = NULL,
ignore_extension = FALSE
)
a list containing a vector of paths called `i_path` and a char with the file format called `i_format`
Path to directory or input files
File format. Defaults to NULL so spectrolab tries to guess it from the file name. Alternatively, use "asd" for ASD; "sig" for SVC (Spectra Vista); or "sed" for PSR (Spectral Evolution)
excludes files that match this regular expression. Example: "BAD"
Boolean. If TRUE, the parser will try to read every file in path regardless of the expected extension.
