https://github.com/adafruit/Adafruit_CircuitPython_hashlib/pull/7 Updated SHA1 constructor to accept optional `data` kwarg to reflect CPython's `hashlib` api: `hashlib.sha1(name[, data])`.

* Added SHA-1 module based on [ajalt's python SHA1 implementation](https://github.com/ajalt/python-sha1).
* Added SHA-1 tests to `hashlib_simpletest.py`

This module implements a common interface to many different secure hash and message digest algorithms. Included are the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 (defined in FIPS 180-2) as well as RSA’s MD5 algorithm (defined in Internet RFC 1321).

SHA1 and MD5 algorithms are not currently supported by the CircuitPython module, but constructors/sub-modules are included in the library to retain backwards-compatibility with the CPython3 `hashlib` module's available algorithms.
