Please bump version and publish to crate

[0b01]

Hi! Thank you for the nice library.

The current version on crate.io is broken. The examples won't run after 1.40 async stablization. Please bump version to 0.0.6 and cargo publish.

I have published the 0.0.6 version to crates.io: https://crates.io/crates/influxdb

Thanks for your support and for using my library. Please feel free to open another issue if you encounter any problems.
