Can't create arbitrary-size BINARY column in SQLite

[timmc]

SQLite does not impose any length limit on binary data, so I would expect to be able to use arbitrary-size binary columns. However, binary() columns are disallowed for SQLite (only permitted for Oracle and PostgreSQL, according to the docstring).

binary(n) is permitted, but doesn't make much sense because SQLite doesn't itself have any column size validation (although I believe Exposed will do that enforcement).

Should SQLite be added to the list of dialects that support unlimited-size binary?

(I can also use blob() columns, which seem more appropriate since that's SQLite's own name for binary-represented data, but I currently am running up against #1442 so having more options might be nice...)

binary column will be backed with BLOB column type. Fix will be available since 0.38.2
