Update dry-initializer to 1.3

[flash-gordon]

One issue related to schema caching showed up after that.

[solnic]

How's performance?

[solnic]

re schema caching, we need to do something smarter because input_schema needs to be recalculated when schema was projected in some way

[flash-gordon]

re performance didn't test, was going to ask you haha. I mean what should I benchmark?

[solnic]

Tests run for me almost 2 x slower

I think our ultimate solution for dry-initializer + rom-rb should be disabling undefined functionality, it adds complexity that isn't justified in any way. WDYT?

[flash-gordon]

@solnic it's kinda hardwired inside the gem atm, we could have our own getters though, I'll give it a try

[flash-gordon]

@solnic dry-initializer now has the undefined: false option that we use to disable UNDEFINED in instance variables,

2.4.0 :006 > require 'dry-initializer'
 => true
2.4.0 :007 > Dry::Initializer
 => Dry::Initializer
2.4.0 :008 > class Foo
2.4.0 :009?>   extend Dry::Initializer[undefined: false]
2.4.0 :010?>   option :foo, optional: true
2.4.0 :011?>   end
 => #<Module:0x007ff24e116b90>
2.4.0 :012 > Foo.new
 => #<Foo:0x007ff24e105d90 @__options__={}, @foo=nil>

Resolved default values stored in @__options__:

2.4.0 :002 > class Bar
2.4.0 :003?>
2.4.0 :004 >     extend Dry::Initializer[undefined: false]
2.4.0 :005?>   option :bar, default: -> { 1 }
2.4.0 :006?>   end
 => #<Module:0x007fb0c50145a0>
2.4.0 :007 > Bar.new
 => #<Bar:0x007fb0c4835690 @__options__={:bar=>1}, @bar=1>

I'm merging this, kudos to @nepalez for helping with this

P.S. Specs are still slower than with 0.11, but that's because of class-level code evaluated on subclassing Relation and/or Command, this won't affect the run-time performance.
