SubIssue for #98. tomland has two step convertion: ``` from Text to 1. Toml (with parse) to 2. Either DecodeException a (with ??) ``` It has function function [parse](https://hackage.haskell.org/package/tomland-0.4.0/docs/Toml-Parser.html#v:parse) for first step and [decode](https://hackage.haskell.org/package/tomland-0.4.0/docs/Toml-Bi-Code.html#v:decode) for both steps, but hasn`t function for second step.
