Proposal: Default env tag

[Artem Yadelskyi]

Hello, I propose to use filed name (to uppercase & to snake case) as default env tag if it's not specified

For example, this struct:

type A struct {
    SomeText string
}

will be parsed the same as this:

type A struct {
    SomeText string `env:"SOME_TEXT"`
}

New option can be introduced that will enable this functionality in order not to make braking change.

This will allow more convenient API for smaller application that do not critically depend on env names.

WDYT?
