Is your feature request related to a problem?

I would like to suggest adding a way to see an estimated price on an imported build (overall & per item), to see a build price before starting it.
I feel searching for prices of gear on a build could rather be automated instead of the user searching one by one (sometimes for many builds)

Describe the solution you'd like

I was thinking how nice it would be to see an estimate of what a build could cost. At the very least the pricing on uniques (as they are a lot more consistent.)

I was thinking about this a bit and 2 ways I thought of that could be a good way to go is either:

1. Use a third party API (There is a project "poe-api-wrappers" which seems to be useful)
2. Give an option to import a dump file from a specific league (current or past) from the poe.ninja dumps.

The idea I had is to create a bit of space to the right of the item to display the price (depending on the method of getting the data as mentioned above).
And then just a drop down of ["day 1", "week 1", "week 2", "end of league / current"] (these dates could be the end of, as id end of week 1.)

The main reasoning behind this is so that users (especially newer) can have a better idea of the costs of a build, see if it could be a potentially viable league start or should rather be an ult.

Given there might be some issues with the logic (of mine) of the feature, but I have no problem brainstorm together.
But I do believe this to be a solid idea and would add major quality of life.

この issue ではファイル、テスト、エントリポイントが指定されていません。まず build のインポート、アイテム表示、データ読み込みの各領域を特定し、価格がサードパーティ API から取得されているのか、poe.ninja のダンプから取得されているのかを明確にしてください。現在または過去のリーグデータを使って、全体およびアイテムごとの推定価格を算出できれば完了です。
