> The conversion from the C# System.Decimal to an Avro logical type decimal is
> not correct. The first 12 bytes of the System.Decimal represent a positive
> unscaled value. This value is passed into a BigInteger constructor.
> However, the documentation of the [BigInteger constructor|
> https://learn.microsoft.com/en-us/dotnet/api/system.numerics.biginteger.-ctor?view=net-9.0#system-numerics-biginteger-ctor(system-byte())]
> states that the most significant bit of the last byte represents the sign of
> the BigInteger. The docs also explain that a 0 byte can be appended to the
> byte array passed to the BigInteger constructor to ensure the value is
> treated as positive.
