Allow Search for hero combinations in the data explorer

[jzhao62]

Is your feature request related to a problem? Please describe. Currently the Data Explorer's hero choice only shows result in OR clause, usually when analyzing a match or review hero plays, you would want to search for heros you played against certain heros, ex: Antimage vs Legion Commander, where LC is a hard counter to AM in certain sense. FIltering matches in high level bracket for antimages played against LC can let user analyze what is the best strategy when the user's team get out drafted, so he can approve

Describe the solution you'd like Add an extra filter (Enemy filter, where you can provide a combination of enemy heros in the draft). I think the API already support it, and this will be a feature where other pro data analytic platforms does not offer

You can probably modify the SQL query to achieve this (but we could maybe add a UI element for it)

i think i can add an extra filter (enemy filter) in the UI so the sql can be auto generated, i will provide a PR for this one

• or add it in the combo page, the combo page could probably add a more detailed filters
• as the Data Explorer page seems only relevant to pro matches

to allow more granular filter in the combo page, like what is available in dotabuff
