generate parquet file from SQLite/basex data

[realmarcin]

The task is to recreate the original parquet file that we used in notebooks for data science and model training. The parquet file is a compressed format that makes a smaller size file and improves loading.

This can possibly be a python script that queries basex and save the resulting table in parquet format.

The original parquet file included all harmonized attributes from the Biosample XML and in addition a set of selected (non-attribute) properties:

primaryId
sraId
sampleName
ownerAbbr
ownerName
taxonomyId
taxonomyName
organismName
status
statusDate
model
package
packageName
title
accession
submissionDate
lastUpdate
publicationDate
dnaSource
entrezTarget
entrezLabel
entrezValue
paragraph
