Update with some braking change

Braking changes list:

• Support open api format JSON Schema: dtsgenerator always target the nodes under definitions node to type output.
• Change interface type name from snake_case to PascalCase.
• Support primitive type to output type definition.

And some bug is fixed.

minor update from v0.6.0

• remove the dependency to asyncblock for async library. I changed async library to Promise because that's next standard.

First stable version of dtsgenerator

dtsgenerator support generating type file from JSON Schema files.
Also it generate type name from id property, and support the reference from $ref property to other node and other schema.
