Bug fixes

• Thanks to @mac01021 we found and fixed the bug that in some cases prevented to resolve schemas with nested case classes and so it was impossible to write them to Parquet

Improvements:

• In an answer to @rtoomey-coatue's request slf4j dependencies were cleaned and hadoop-client was marked as provided. It allows developers to define their own version of Hadoop and avoid solving dependency conflicts. The library is more lightweight now.
• Support for following types was added:
  • Byte
  • Short
  • Char
  • BigDecimal

Many thanks to all contributors!
