   Additional notes2 sources agree

   • Fixed issues where fields in structs that were not defined in the schema raised errors (array, slice, time, map)
   • Added support for reflect encoding/decoding of additional types to/from parquet types
     • Go type <-> Parquet type
     • int <-> int64
     • int32 <-> int64
     • int16 <-> int64
     • int8 <-> int64
     • uint <-> int64
     • uint16 <-> int64
     • uint8 <-> int64
     • int64 <-> int32
     • uint64 <-> int32
     • uint32 <-> int32
   • Removed some inconsistent api behaviors
     • reflect marshaling/unmarshalling now ignores fields not defined in the schema (this already happens when the marshaller is used by floor.Writer and goparquet.FileReader)
     • int32PlainDecoder and int32PlainEncoder now no longer support uint values
   • Added function IsAfterUnixEpoch to allow test whether a timestamp can be written as Julian date.
   • Allowed setting selected columns after opening a parquet file through SetSelectedColumns method.
   • Fixed dictStore to correctly reset valueSize which should reduce size of written files.
   • Fixed reflection-based marshal/unmarshaling for some basic types.
   • Fixed DECIMALs computation of maximum amount of digits.
   • Improved parsing of legacy timestamps.
   • Allowed reading of file metadata before properly opening a parquet file.
   • Added method SeekToRowGroup to allow seeking to specific row groups.
