Support for zero-item inline tables

[Alan Viverette]

TomInlineTable in ktoml-core-jvm:0.5.0 throw a ParseException when it encounters a zero-item inline table.

For example, consider the following line of valid (per language docs) TOML:

ACTIVITY_COMPOSE = {}

This yields the following exception:

ParseException: <...>: Incorrect format of Key-Value pair (missing equals sign). Should be <key = value>, but was: . If you wanted to define table - use brackets []

Sounds like a new feature, unfortunately all contributors are busy even with fixing bugs, so I do not know if it will be fixed soon, sorry. But I will definitely try ;(
