feat: sponsees mode

Description

This is a preliminary idea, and I'm unsure if it's the right fit. This PR adds a sponsoring mode to display a person's total sponsorship history. Here's an example.

https://github.com/hyoban/sponsors

const mode = process.env.SPONSORKIT_MODE as "sponsor" | "sponsoring";

export default defineConfig({
  mode,
  tiers:
    mode === "sponsor"
      ? [
          xxx
        ]
      : [
          xxx
        ],
  outputDir: `./sponsorkit/${mode}`,
});

Additional context

Do you mean that instead of using monthlyDollars, you want to count for the total sponsorship for tiers?

I found the words "mode" and "sponsoring" a bit confusing. Maybe instead, we could introduce a totalDollars field in the Tier definition so the tier can be used based on monthlyDollars or totalDollars based on users' config?

No, I want to show who a person sponsored. Like https://github.com/antfu?tab=sponsoring

I see. I would love to have it. For the naming, maybe mode: "sponsors" | "sponsees"?
