CITEseq MAE to SCE conversion improvements

[drighelli]

the function .CITEseqMaeToSce in CITEseq.R file has a few issues:

• doesn't return metadata for peripheral_blood dataset
• doesn't add the new clr counts to the altExps of ADTs for cord_blood dataset
• it can be written by thinking in a more general way where each assay of the MAE is a SCE that can be combined as main and altExps assays in the new SCE returned object

Would be good to address this before publication @drighelli

Thanks @lwaldron I'll work on it.
