Allow arrays to be specified @nonNull

[LasseBlaauwbroek]

At the moment, there seems to be no way to specify that the elements of an array are non-null. I'd propose an extension for array types:

@nonNull field            ----> [Field]!

@nonNull field[]         ----> [Field!]

@nonNull field[]         
@nonNull field            ----> [Field!]!

Hey there, this plugin is a bit obsolete. The @notNull smart comment is available in PostGraphile as a built-in. This plugin is mostly useful for its PgNonNullRelationsPlugin part.

I'd recommend opening an issue over at graphile/postgraphile or joining the Discord channel and making an inquiry there.
