Changes due to PureScript 0.15
1. Remove constraints from foreign imports.
2. Remove support for records due to the new apartness check.
3. Convert CommonJS to ESmodules
Others:
Format all files.
TODO:
Records are currently not supported because of the new apartness check
in PureScript 0.15. The instance (Typeable (f a)) then partially
overlaps with (Typeable (Record r)). Even though (a::Type) and (r::Row
Type), that still isn't enough for the compiler to disambiguate. There
is no way that I can see to specify an instance for all (f a) where f is
NOT Record.
