Post-process data from ClickHouseHTTP to speed-up a little their access

Change default DBI backend to ClickhouseHTTP.
Allow selecting alternative driver. The 2 following are supported: ClickhouseHTTP::ClickhouseHTTP() and RClickhouse::clickhouse()

Avoid unnecessary data type conversions

Expanding matrix support to the Matrix class from the Matrix package to support sparse matrices.

Checks can be bypassed when creating memoMDB, fileMDB, chMDB and metaMDB (check=FALSE): it make the creation of the object faster but it should be used only when the user knows what she/he is doing with the data and the model.

Display in explore_MDBs():
maintainer is displayed in MDB table
markdown tags maintainer and title are rendered in MDB table
list_MDB.chTKCat() filters DB based on MDB and Public tables

Support versioning of tables in chMDB using timestamps.
Support base64 data type.

filter_mdb_matrix(): Filter a matrix stored in an MDB

Supporting matrix (ReDaMoR >= 0.5.0)

A user can be a data consumer (default) or a data provider (set the "provider" setting to TRUE). A data provider can create and manage a database.
