feat: function to create a QFeatures object from DIANN output

[cvanderaa]

I moved readSCPfromDIANN() from the SCP.replication repo to the scp packages.

Upon request (see https://github.com/UCLouvain-CBIO/SCP.replication/issues/23), I also added an argument ecol to select the column that contains the quantitative information.

I still need to perform the following tasks before considering this issue solved:

• [ ] Comprehensive unit testing
• [ ] Improve documentation: add examples
• [ ] Refactor: the code is too long and difficult to understand

@KristinaGomoryova, you can play with the new argument after installing the development version of scp:

BiocManager::install(UCLouvain-CBIO/scp)
library(scp)
?readSCPfromDIANN

Thanks a lot, I'll try it right away!

This issue is now solved in QFeatures since https://github.com/rformassspectrometry/QFeatures/commit/c895bbc0ed7be1db22dfaa78bef33bd85607933c and propagated to scp since bca81626bce93daadba55d846aae60ce4f0a7dfe
