spectra.alignment: Align spectra with different spectral resolution
In RamanMP: Analysis and Identification of Raman Spectra of Microplastics

The function merges spectra with different spectral resolution using as a reference the spectra with highest resolution. The matching is done based on a span value defined by the user.

1	spectra.alignment(db1, db2, t)

`db1`	Dataframe/matrix with frequency values as first column and at least one column with intensity values.
`db2`	Dataframe/matrix with frequency values as first column and at least one column with intensity values.
`t`	Numeric. It indicates the tolerance for the matching of the two spectra. For a given t-value, the intensity values that range in the frequency interval (f-t, f+t) are matched with the corresponding intensity values of the database with the highest spectral resolution.

Return a matrix with frequency of the database with highest spectral resolution and intensity values of the two databases matched based on the 't' parameter.
