field_id support in Class Serialization

[tliu1-illumina]

I'm writing Parquet files for data lakes and need to set the field_id metadata. Seems like there is current support for this by setting DataField.FieldId.

However, I would much prefer to use the higher level Class Serialization vs having to do it the low level way which is getting quite messy.

It would be great if we can add attributes to the fields to specify FieldId in the class, and class serialization will understand it. For example:

class Record {
    [FieldId(1)]
    public DateTime Timestamp { get; set; }

    [FieldId(2)]
    public string EventName { get; set; }

    [FieldId(3)]
    public double MeterValue { get; set; }
}

...

await ParquetSerializer.SerializeAsync(data, "/mnt/storage/data.parquet");

Seems like this can be done in the ConstructDataField() function https://github.com/aloneguid/parquet-dotnet/blob/master/src/Parquet/Serialization/TypeExtensions.cs#L142-L193

What do you think? Will this work? Would be happy to do a PR.
