This removes checks for "file out of bounds" to cram-js

While the code is a bit "safer" perhaps with these checks, they require that "stat" works which requires specialized CORS headers to be set. Access to files for example https://ftp.1000genomes.ebi.ac.uk/vol1/ftp/data_collections/HGDP/data/Sindhi/HGDP00171/alignment/HGDP00171.alt_bwamem_GRCh38DH.20181023.Sindhi.cram work with this PR enabled, but not without this PR

Draft PR because tests may be non-passing, but tested in the genome browser

an alternative is making these checks "optional" so they are applied if the stat result is available so you get some partial safety from this

@cmdcolin cmdcolin force-pushed the remove_stat branch 2 times, most recently from 464e899 to 2ce6ccf Compare November 7, 2024 15:41

Revisited this PR to fetch files from external buckets we don't necessarily have control of e.g. this file https://ont-open-data.s3.amazonaws.com/colo829_2024.03/wf_somatic_variation/sup/COLO829_tumor.ht.cram which is from the ONT bucket. the bucket has CORS enabled, but not CORS for Content-Range header access. this makes it fail when trying to get the stat() for "file length"

This PR removes the file length checks

it passes all tests except 1 currently
