HOTP and TOTP implementation in C# targeting .NET standard 2.0, compliant with RFC 4226 (HOTP) and
RFC 6238 (TOTP) and verified against supplied test vectors. The interface includes support for
multiple algorithms (HMAC-SHA1, HMAC-SHA256, HMAC-SHA384, and HMAC-SHA512), code lengths (6 - 10),
and an adjustable period, or time step, (1 second - 1 hour) for TOTP.

The reason for creating this library was to fetch multiple HOTP counters or a TOTP time range in
a single call.

A parser for OTP Auth URIs is also included that conforms to the documentation found at:
https://github.com/google/google-authenticator/wiki/Key-Uri-Format.

This implementation also includes a Base32 encoder and decoder. It is compliant with RFC 4648,
using the standard alphabet from section 6, and has been tested against the test vectors from
section 10.
