Initial support for OrcaBus API

[pdiakumis]

A few enhancements for handling OrcaBus workflow runs. Most of these will likely be replaced in the near future by better wrappers based on the OrcaBus OpenAPI spec.

• new functions:

  • envvar_defined: better replacement for envvar_undefined to check AWS/ICA env vars
  • jwt_exp: checks JWT expiry date
  • jwt_validate: validates JWT
  • orca_jwt: retrieves orcabus/token-service-jwt from AWS Secrets Manager
  • orca_libid2workflows: generates tibble with workflows for a given libid
  • orca_prid2wfpayload: generates workflow payload for give prid
  • orca_query_url: query given endpoint (name could've been simply query_url)
  • orca_workflow_list: generates tibble with list of workflows (can specify type of workflow to return)

• deprecated functions:

  • awsvault_profile: now just using AWS env vars (e.g. via granted)
  • envvar_undefined: replaced with envvar_defined

• refactored functions:

  • meta_rnasum: handle newer umccrise field from v1.1.0 onwards

• pre-commit: bump 0.4.2 -> 0.4.3

• dependencies: import httr2, jose, paws for OrcaBus queries
