What's changed and what's your intention?

In greptimedb, we store waypoints of a path row by row. However, when using with data process or visualization software, it treats a trajectory as a single value, either in geojson or other formats.

This patch introduces a new uadf geojson_encode_path that takes rows of latitude, longitude and timestamp to output a path that compatible with deckgl's path input.

It also refactors our macro for aggregation function to remove use from macro to avoid multiple use error when using the macro.

sqlness tests included.

Checklist

  • I have added the necessary unit tests and integration tests.
  • This PR requires documentation updates.

    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.

    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

The return type is not geojson at all. It's just compatible with geojson's
coordinates part and superset's deckgl path plugin.
