Duplicate Column

[FabianHertwig]

Hey, thank you for this repo!

When I try to convert my export, I get a multiple column error. Here is the stack trace:

sqlite3.OperationalError: duplicate column name: metadata_Meal

I think the issue is that I have records like these:

 <Record type="HKQuantityTypeIdentifierDietaryCholesterol" sourceName="MyFitnessPal" sourceVersion="35120" unit="mg" creationDate="2021-07-04 20:55:27 +0200" startDate="2021-07-04 20:55:00 +0200" endDate="2021-07-04 20:55:00 +0200" value="124">
  <MetadataEntry key="meal" value="Dinner"/>
  <MetadataEntry key="Meal" value="Dinner"/>
 </Record>

And if sqlite is case insensitive, then metadata_meal and metadata_Meal result in the same column.
