Average waste rate not computing

[AnnieMungai]

• Include wastage in the stock module.
• Average wastage, not computing.

@AnnieMungai I wouldn't know where to begin implementing this new feature. There is no definition of "wastage" or a formula to calculate it, nor instructions on where this should be added in the current app. For average wastage, a link to the current formula to verify against would be helpful, and steps to replicate the issue that it's not computing.
