refactor schemas to support sprite2 and sprite3 files, while reusing rules in common with sb2 and
sb3 files
BREAKING CHANGE: Change to main API which now takes an additional boolean argument indicating
whether a sprite or project is being validated
Added sb3 schema, renamed sb2 schema, and updated validate to check given input against both sb2 and
sb3 schemas. Validate appends a projectVersion to the given project with 2 or 3 if the given project
is valid against the corresponding schema. Validate now returns an object containing an error
message and both the sb2 and sb3 validation errors upon failure to validate against both schemas.
BREAKING CHANGE: Changes to validate API and what it returns (namely, error returned by validate is
no longer a string, but is now an object which contains an error message string as well as the sb2
errors and the sb3 errors). Users of this library function should expect to parse the given error to
figure out why validation failed.
