Bump github.com/BurntSushi/toml from 1.1.0 to 1.2.1

[dependabot]

Bumps github.com/BurntSushi/toml from 1.1.0 to 1.2.1.

Release notes

Sourced from github.com/BurntSushi/toml's releases.

v1.2.1

This release fixes the omitempty struct tag on an uncomparable type panicking.

v1.2.0

This release adds a few additional features:

• Support encoding and decoding json.Number, making interoperability with JSON when using json.Encoder.UseNumber() easier.

• Support time.Duration string format; an integer will be interpreted as nanoseconds (like before), but a string like "5h" will be parsed. On encoding the string format is used.

• The omitempty struct tag now also works for structs with all zero values, for example an empty time.Time. A struct is considered "empty" when all fields (exported and private) are the zero value.

• Allow using interface{} (or any) as the map key when decoding.

And some fixes:

• Fix encoding.TextUnmarshaler not working for map values.

• Make encoding.TextUnmarshaler and toml.Unmarshaler work if MarshalText() or MarshalTOML() have a pointer receiver.

• Error out on nil returns from MarshalTOML/MarshalText; before they would get encoded as invalid TOML (keyname =).

• Fix a panic where it would try to encode array = [{}, 0] as:

  [[array]]
  [[array]]
  

  Which isn't valid as 0 isn't a table.

• Some better error reporting for some errors.
