✨ option to filter buy order that the bot can't afford to buy

[idinium96]

To enable this feature, pricelist.filterCantAfford.enable must be set to true (it's false by default).
Note that, this feature will only do its job every 30 minutes IF the missing OR re-adding items is less than 1000 items, otherwise, it will do this job again after 60 minutes.

How does this feature work?

Let's say your bot currently has 6 keys, 150 ref in their inventory on start. If you have this feature enabled, then your bot will NOT create buy orders for items with buying prices of more than 6 keys AND more than 150 ref.

Let say you have these in your pricelist (item - buying price):

• Strange Splendid Screen - 7 keys, 19.77 ref
• Genuine Maul - 6 keys, 19.77 ref
• Strange Loose Cannon - 5 keys, 24.22 ref
• Strange Ullapool Caber - 5 keys, 12.22 ref
• Strange Festive Flare Gun - 4 keys, 26.55 ref
• Genuine Sharp Dresser - 4 keys, 20.77 ref

At first, your bot will only NOT list Strange Splendid Screen because the buying price for keys is more than what currently your bot has.

Then let say your bot made some valid trades and suddenly your bot's pure is now 5 keys 20 ref. Now you'll see that all these buy orders are all hidden in backpack.tf (once backpack.tf fully load your bot inventory data):

• Strange Splendid Screen [(5 >= 7 - false) AND (20 >= 19.77 - true) = false];
• Genuine Maul [(5 >= 6 - false) AND (20 >= 19.77 - true) = false];
• Strange Loose Cannon [(5 >= 5 - true) AND (20 >= 24.22 - false) = false];
• Strange Festive Flare Gun [(5 >= 4 - true) AND (20 >= 26.55 ref - false) = false]; and
• Genuine Sharp Dresser [(5 >= 4 - true) AND (20 >= 20.77 ref - false) = false]

All of these hidden buy orders (can't afford) will be removed once the automatic check for missing listings OR auto-relist is executed. The bot will NOT update it immediately.

Then let say your bot is back to have enough pure to buy those items, then it will be added on the next automatic check for missing listings OR auto-relist. If the items that are missing OR need to be re-add are more than 1000 items, the next automatic check for missing listings will be executed in 1 hour, else, it will be executed in 30 minutes.

If you're using this feature, please expect your bot buy orders will never get fully listed UNLESS your bot has enough keys and pure metals to buy it.
