allow decoding byte string without padding

[jad-elmourad]

What was wrong?

closes #198

How was it fixed?

@jad-elmourad:

• Allow decoding arbitrary length bytes without padding

@fselmo:

• Introduce this as a feature by allowing the default "strict mode" behavior for the BytesStringDecoder to be turned off via a strict flag that is True by default. The current behavior of the library is strict=True so this shouldn't be a breaking change. When strict=False, the behavior desired in #198 is enabled.

• Add some testing around this and make sure all other decoding tests pass whether the strict flag is True or False.
