Combine exported types into one file

[meduzen]

Closes #93.

• test result of found types using Typedoc (before and after changes): it should get rid of unwanted types unneeded
• try the project (link locally) (before/after) and compare DX

Testing in a TS project:

datetime-attribute 1.3.4…

• doesn’t export all types from its root, but from their sub-path: import type { Precision } from 'datetime-attribute/types/datetime'
• exports a non-existing type from an internal function that is not exported: import type { round } from 'datetime-attribute/types/utils/math' (code)
• properly exposes the exposed functions

datetime-attribute with this PR (using npm link) solves all previous problems and properly exposes the right stuff. It also exposes all the package source files because of npm link.

But in a JS project, the types import is not working anymore with this PR using /** @type {import('datetime-attribute').Precision} */. Following 148607b it works again.

Gonna do a pre-release later to test it from a package registry.

Gonna do a pre-release later to test it from a package registry.

Seems to be the right shot according to test done with 1.4.0-rc.0.
