time_vector::pipeline::lambda module is falling out of date

[epgts]

The experimental time_vector::pipeline::lambda module is suffering from a bit of neglect.

Same problem in two pull requests we're using old and deprecated code and clippy is upset:

• cargo update atomic-polyfill and cpufeatures #610
• Time Vector Templates #638

Some options:

• update the lambda stuff
• remove the lambda stuff
• see if we can get clippy to ignore these deprecations
• see if we can update pest less hard
