func ApplyEnvOverrides

func ApplyEnvOverrides[T any](prefix string, c *T, delim string) error

ApplyEnvOverrides overrides field values from environment variables

fields must be tagged with `env:"env_key"`

only works on exported fields

fields without an env tag are ignored fields with an `env:"-"` tag are ignore

sub-structs are recursively parsed (if they have an env tag) and the env-variable keys are delimited by the delim parameter sub-structs with `env:""` are also parsed, but the delimited is skipped (they are handled as if they were one level higher)
