Improve performance of Add Formulation

[dipalichippa]

Performance degradation is observed primarily in scenarios where enforce_order = true.

In general, it takes ~10-15 seconds to load a formulation using {sheet}.add_formulation -- for historical data loads where customers provide thousands of formulations it can take upwards of 8 hours to run. Is there a "bulk" method we could use?

@jmohin It's taking around 30 sec to 3 mins depends on number of ingredients per formula.
This impacts the performance during bulk upload.
