Proposal

Currently we use 3 packages to handle URI:

• league/uri (for general handling of URI)
• league/uri-components (for URI component handling)
• league/uri-interfaces (for common classes/interfaces between both package listed above)

We should maybe create a monorepo to improve maintenance around those 3 packages.

As I am not familiar with creating monorepo some external help would be appreciated for setting up the monorepo.
