Feat: add optional optimistic logistics requests

[ScottHarwoodTech]

Sometimes people place Blueprints and do not have all the required resources to start the build. Some people would like the option to allow a request_items job to timeout and let it the job start. This is achieved using the following logic:

• Added a setting of logistics_fullfillment_timeout when set to -1 disables all the timeout logic.
• Added a setting of optimistic_logistics_items which is a comma delimited list of items that we would LIKE to place but if we dont have them we can still attempt to place them (think modules)
• When the request_done is evaluated we check to see if the logistics_fullfillment_timeout has lapsed if it has we get what different item types havent been fulfilled, if the only items havent been fulfilled are optimistic then we will mark the request_items job as done

• When the get_job method is evaluated when we get to the request_items job definition we dont add it the only items in the combined_chunks.requested_items table are optimistic (to avoid empty bot looping)

Notes:

This is still a draft so the code absolutely needs to by DRYed up.

I am not a lua dev so its probably not the best code 😂

Looks like my editor has done a lot of changes to formatting 😭

I've not checked everything yet but it looks decent so far from the technical side.

Looks like your formatter got unhappy at a lot of places and decided to rip things apart.

yup, the formatter is not happy one bit.

@fgardt Ive sorted all those whitespace issues and rebuilt the logic into something much more legible and assessible.
