Better benchmarking

Could use some streamlining. Maybe look into AirspeedVelocity.jl

Code lives here: https://github.com/JuliaAstro/Photometry.jl/tree/main/bench

In case it helps, I run AirspeedVelocity benchmarks on one of my repos; benchmark code is here and then the benchmark.yml file is here.
