Add `--verbose` mode for LSIF Typed->Graph conversion tool

Created by: olafurpg

Currently, the LSIF Typed->Graph conversion tool silently ignores invalid input such as incorrectly encoded ranges. It would be nice if this tool included an optional --verbose flag to print warnings for these programming errors or a --strict flag to fail fast on invalid payloads.

Search for the literal https://github.com/sourcegraph/sourcegraph/issues/31415 to find locations where we should log a warning of fail fat.
