Go mod tidy breaks when importing

[graytonio]

After implementing the module into some code I ran go mod tidy to clean up the dependencies and was met with this error:

go: finding module for package github.com/chainifynet/aws-encryption-sdk-go/mocks/github.com/chainifynet/aws-encryption-sdk-go/pkg/model
go: jfrog.com/pe/aws/encryption imports
        github.com/chainifynet/aws-encryption-sdk-go/pkg/providers/kmsprovider tested by
        github.com/chainifynet/aws-encryption-sdk-go/pkg/providers/kmsprovider.test imports
        github.com/chainifynet/aws-encryption-sdk-go/mocks/github.com/chainifynet/aws-encryption-sdk-go/pkg/model: module github.com/chainifynet/aws-encryption-sdk-go@latest found (v0.2.0), but does not contain package github.com/chainifynet/aws-encryption-sdk-go/mocks/github.com/chainifynet/aws-encryption-sdk-go/pkg/model

I believe this is the mocks that are generated by mockery but they are not included in the releases.

Good catch @graytonio, thanks!

Fixed in v0.2.1
