feat: add bun build to the benchmark

[LuggaPugga]

Closes #4 by adding bun tests for all of the benchmarks.
Let me know if you have any questions or feedback

Seems like Bun.build() is sometimes faster than rolldown , but then it might just be due to the runtime. It could be interesting to see how it compares to a Bun run rolldown .

Yeah i could look into adding that as well.
Maybe even adding the --bun flag
