bump schemars to 1.0

[mdepta42]

Bump version of schemars to recently released 1.0.

Changes incldue:

• Module paths updates.
• Schema definition has been rewritten using json_schema macro.
• JsonSchema trait definition was changed, most notably is_referenceable has been changed to inline_schema(see and see)
• tests have been updated to account for new schemas now using serde_json::Value internally see

I'm no expert at the schemars internals so everyone please feel free to correct / improve upon the current implementation.

Can we keep schemars 0.8 support while adding a separate schemars1 feature, so this is not a breaking change? (Then we can remove the 0.8 support in a future major version.)

Note: The test failures are fixed by #175.

[mdepta42]

Oh yeah absolutely. An alternative I've been considering is to add support for ordered float over in the schemars crate. They provide support for many common crates, and use the dependency versioning scheme using features you've suggested.

I'm okay with either approach.
