Invalid value in BSOQueryParams

[jrconlin]

An error is being generated during deserialization of the BSO Query parameters. I'm not sure which value is triggering it, but it appears to be one of the numerics.

Possibly from SyncTimestamp::from_header

Yeah, possibly. It could be related to a bad date format or something.

To be honest, I'm starting to not be a fan of the serde habit of just puking when it hits an error, particularly when we don't have a reproduceable state. I may add an extra field for this error that shows what got fed to serde to at least help isolate some of it.
