implement `{maldipickr}` using the RforMassSpectrometry improved codebase

[cpauvert]

• MALDIquant and readBrukerFlexData both require a lot of maintenance
• the packages at RforMassSpectrometry have an improved backend
• implementing maldipickr with it could be relevant for long-term
• but still needs to import some of the MALDIquant routines Integrate MALDIquant's baseline estimation rformassspectrometry/MsCoreUtils#119
