`jsontoml` is very similar to `tomljson`
It uses json.Unmarshal to convert read json to map and then
converts the map to tree using `toml.TreeFromMap`.
Then this tree is converted to toml using `tree.toTomlString()`
The numbers when taken as input from json get converted to float64
because of how `json.Unmarshal()` converts all json numbers to float.
Fixes#280
* Port toml-test to pure Go
This change basically ports the toml-test examples test suite to pure
Go. This removes the snowflake test.sh required to run such tests, and
allows us to the example tests on any platform (which includes Windows
as part of the pull-request testing).
* Allow CircleCI failure for go tip
