Add support for missed tarantool types

[pavlua]

Added support for some missed tarantool types, implemented as msgpack extensions:

• Decimal type https://www.tarantool.io/ru/doc/latest/dev_guide/internals/msgpack_extensions/#the-decimal-type
• Uuid type https://www.tarantool.io/ru/doc/latest/dev_guide/internals/msgpack_extensions/#the-uuid-type
• Datetime type https://www.tarantool.io/ru/doc/latest/dev_guide/internals/msgpack_extensions/#the-datetime-type

Added new test suites with integration tests:

• tests with serialization and deserialization tests for almost all Tarantool types, including new ones (decimal, uuid, datetime)
• some basic tests for getting schema and inserting value into space
  To launch tests locally you need only empty Tarantool instance, you can run it using docker-compose, for example
