make lzo an optional dependency (alternative to pr #79)

[jeffbski]

This is an alternative approach to #79 based on @vweevers comment.

Since lzo requires a native compilation step as part of its install make lzo an optional dependency that is only required when it is that feature is attempted to be used. We hide lzo behind a function.

LGTM @kessler

Is there any chance this (or #79) will get merged into master? We were getting errors when using this on AWS Lambda, because LZO needs to be compiled for Lambda's architecture. Applying this PR resolved it :)

I'll take a look at this over the weekend.
