Fix anyhow dependency issues (#208)

- Do not require backtrace feature
- Starting version 1.0.77, anyhow gathers backtrace is std feature (enabled by default)
  is specified even if backtrace feature is not enabled.
  Therefore specify default features as false.
- Specify version 1.0.45 since that is the minimul version required to successfully
  compile regorus
