Updates to the DMP metadata extractor Lambda for COKI

[briri]

• Update the file size limitation of the DmpExtractor lambda to allow a single file to be 100MB (currently set to 10MB)

Cleanup needed on the DmpIndexer needed:

• Remove grantId regexes. There is not enough consistency to manage these. COKI will handle the cleanup on their end
• Some of the list fields contain empty objects rather than strings or having an empty list: funders, funder_ids, grand_ids, see DMPs doi.org/10.48321/D1TG9N, doi.org/10.48321/D18C88. For example: "funders":[{}] "grand_ids":[{}]
• The description field sometimes has a boolean value rather than a string or NULL, see DMP doi.org/10.48321/D114471AC3
• The modified field sometimes has a boolean value rather than date, see DMP doi.org/10.48321/D114471AC3
• The project_end and project_start fields sometimes have boolean values rather than a date, see DMP doi.org/10.48321/D1MD2F
