Looked at a debugger and it is something we can make better, just need to
update `org.apache.cassandra.cql3.functions.FunctionParameter#inferType` for
our arg type (we currently use `FunctionParameter.anyType(true)`)
We get `null` when doing `arg.getCompatibleTypeIfKnown(keyspace)` as we have
no clue what it could be... but we do have access to the other args + receiver
type... so for vectors we could just assume that any of the 2 other variables
we have access to are defined... if non are defined we fail with this type
cast...
I am not including this `VectorFct` class in this PR as I don't define any
functions... but it doesn't seem bad to get `assertRows(execute("SELECT
similarity_cosine(value, ?) FROM %s WHERe pk=0", vector(1f, 2f)),
row(vector(1f, 2f)));` working
