Bad error message for incorrect dependency

[austinabell]

The error message, if someone has the near-sdk dependency as anything like near-sdk = "4.0.0" or near-sdk = "4.1.0-pre.1, the error message is:

ERROR: near-sdk dependency should be a table

Which is very unhelpful and does not indicate why this is failing. Ideally, for previous versions it should indicate what the minimum SDK version supported is, and for ones that don't apply the abi feature, it should either indicate that it is required or be able to add that feature automatically.

Adding this as another error message that is bad:

the package `non-fungible-token` depends on `near-sdk`, with features: `__abi-generate` but `near-sdk` does not have these features.

This depends on near/near-sdk-rs#893 (which hasn't currently been merged or released) which will be unusable unless you know that.
