Implement `lambkin-export` to common data formats

[hidmic]

Feature description

LAMBKIN collects a lot of data for each benchmark run, which is then made available through lambkin.data APIs. This is fine and all, but it is overkill for many uses cases. Sometimes, you just need to look at the data on a spreadsheet. Having a CLI to quickly export benchmark data to common formats such as .csv would simplify some workflows.

Definition of Done

• Update lambkin.data APIs to collect all data by default e.g.:
  • Trajectory and metric names in lambkin.data.evo.stats() should be optional
• Add an export verb to the lambkin CLI to output lambkin.data frames in CSV e.g.:
  • lambkin export [-f csv] [-i path/to/input] [-o output.csv] evo.stats
• Update export verb to take filtering predicates on benchmark iteration metadata e.g.:
  • lambkin export -k "variation.parameters.some_parameter == 100" evo.stats
