Warn when Koanf read fails (#47)
Figured out the problem in issue #32, the toml file syntax was invalid (I had `'` instead of `"` at some values), but there was nothing in the logs about it.

Moved the config reading (and watching) into the same function, which logs the error as a warning.

I wanted to try moving the whole `if` into a separate function, but I kept getting errors when I tried to extract the `path` from the `File`, so I have that attempt in a separate branch not in this pull request: 5a84bf8148
