Update MSRV to 1.71 and add CI test (#589)

Update MSRV in Cargo.toml and Readme to be up to date with the
dependencies that we're using, plus add a test to check that we don't
deviate from it.

The dependency causing the bump is `env_logger` with a MSRV of 1.71
(released July 2023)
https://github.com/rust-cli/env_logger/blob/9303b0c0393c33046a791b0a6497b0f03ef1f434/Cargo.toml#L8

The issue seems to also be affecting other crates in the workspace that
don't depend on that crate because the MSRV bump is due to some cargo
changes regarding `dep:` features and so it seems to affect the version
resolution of the entire workspace.

Note that this required a small change to exporters, apparently older
rust versions have trouble disambiguating the `csv` crate with the `csv`
module.
