Improve Micro::Case internal steps [NEW FEATURE]

[serradura]

• Support Method instances as an alternative to lambdas. Use Method#arity to define when it will receive or not the result #data values.

Micro::Case::Result#then

class ContractaTemplate::Update < Micro::Case
  attributes :params, :contract_template
  
  def call!
    find
      .then(method(:validate))
      .then(method(:persist))
      .then(method(:create_revision), some: :hash)
  end
end

Micro::Case::Result#|

class ContractaTemplate::Update < Micro::Case
  attributes :params, :contract_template
  
  def call!
    find \
      | method(:validate) \
      | method(:persist)  \
      | method(:create_revision)
  end
end

• Make the Micro::Case::Result#then accumulates the data when receiving a lambda or a method instance.
