requests: Rename urequests to requests.

This module implements a subset of the Python requests module, and so
it should have the same name.

Added a backwards-compatibility wrapper to allow people to continue to use
`import urequests`. This lives in micropython/urequests.

Changed requests to be a package, so that we can implement extension
packages in the future for optional functionality.

Added a basic README.md to both.

This work was funded through GitHub Sponsors.

+## urequests compatibility
+
+The MicroPython version of
+[requests](https://requests.readthedocs.io/en/latest/) was previously called
+`urequests` and a lot of existing code depends on being able to still
+import the module by that name.
+
+This package provides a wrapper to allow this. Prefer to install and use the
+`requests` package instead.

+## requests
+
+This module provides a lightweight version of the Python
+[requests](https://requests.readthedocs.io/en/latest/) library.
+
+It includes support for all HTTP verbs, https, json decoding of responses,
+redirects, basic authentication.
+
+### Limitations
+
+* Certificate validation is not currently supported.
+* A dictionary passed as post data will not do automatic JSON or
+  multipart-form encoding of post data (this can be done manually).
+* Compressed requests/responses are not currently supported.
+* File upload is not supported.
+* Chunked encoding in responses is not supported.
