Does not work without specifying schema

[oschwald]

When using the binary from the release page or building master from the source, the command fails when a schema has not been specified:

[!] No schema specified, will run without table and column validation.
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x870c29]

It appears that s.Schema is nil in vet.NewContext(tables: s.Schema.Tables).

Reproduces for me too with [email protected]

could you try adding a nil check in there and pass in an empty map when schema is nil?
