Remove duplicate datatype files

[siddhpant]

There are some datatype files which are present, for example, long_java and long_d.

They should be removed, since duplicates are generally not required.

The new names of datatypes should allow it to be clearly differentiated from others and should be related to the concerned datatype.

@StevenCheswick, ask @jayvdb or someone on gitter/zulip. I'm not the owner of the repo.

Doesn't hurt to contribute anyway.
