`recordId` vs. `recordid`

[msbarry]

The "source" field of some elements has the key recordid (all lower case) but other elements have the key recordId (upper case I).

I discovered this when parsing overture data with planetiler and had to add this workaround:

https://github.com/onthegomap/planetiler/blob/15b939b2b717d804e7d2fb50f0be8d25e0d466b9/planetiler-core/src/main/java/com/onthegomap/planetiler/overture/OvertureSchema.java#L609-L615

As of 2023-10-19, an entry in sources is represented as a struct instead of a map<string,string> in the parquet files, so it is now consistent:

sources: array<struct<property:string,dataset:string,recordId:string,confidence:double>>
