[ENH] Include data processing steps, reference to which the reads were aligned or if possible lab protocol into the main table

Is your feature request related to a problem? Please describe.

I was wondering whether it is possible to also retrieve data processing description that is present in the sample's records in GEO. See here for an example: https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM6005004 - there is a lot of information that we would like to see in the table that pysradb generates:

Status
Title
Sample type
Source name
Organism
Characteristics
Treatment protocol
Growth protocol
Extracted molecule
Extraction protocol
Library strategy
Library source
Library selection
Instrument model
Description
Data processing

I like the table that is currently generated using the following: df = db.sra_metadata(df["study_accession"], detailed = True, expand_sample_attributes = True, output_read_lengths = True) although I feel like it is missing sometimes crucial information that is only included in GEO under specific records of the samples. For an example it the record of the sample that I have included above you can find the following:

Sequenced reads were trimmed for adaptor sequence and low-quality sequence (bbduk; minlength=30, qtrim=rl, trimq=15)
Reads were then mapped to the reference genome of Mus musculus (GRCm38) using STAR aligner version 2.5.3a with parameters --quantMode GeneCounts --runThreadN 4
Assembly: GRCm38

It would be nice to get that into the sra_metadata table too if that is possible. I guess for now I could just use geoquery for that and then merge two tables if possible by GSM sample ids, although I would need to test that. Then probably the hustle including this here would be redundant. But still it seems like a nice direction that one could take to expand this :)

Thank you for your work so far!
