error non-unique values when setting 'row.names' in `process_spectra()`

[cpauvert]

this error can happen when multiple spectra have the same name, which should not happen with proper research data input but can arise during data analyses.

At the moment, the function stops. An improvement would be to exit gracefully at least, or provide a solution (would make.unique() be possible or too intrusive?)

I see two possibilities:

1. allow a list of names to be passed to process_spectra() instead of using the fullName metadata as the fullName might not be always the most relevant name
2. have an extra function that create a tibble of putative names (based on fullName), check for uniqueness, and can be passed on to the process_spectra()

Option 1

• it's a fix that does not break anything, but hard for users to check the validity of names, trust the vector order(?)

Option 2

• a get_spectra_names() that could be invoke by default (see below for toy example)
• process_spectra still expects a tibble, but either it is given by the user for custom nomenclature, or the default with the fullName metadata is used.

process_spectra(spectra_list, names = get_spectra_names(spectra_list))
