Fix date input conflicts

[dalpo]

Starting from phoenix_html v2.11.0, this library define internally the date_input function which is causing a conflicts with local torch function:

== Compilation error in file lib/torch/views/filter_view.ex ==         
** (CompileError) lib/torch/views/filter_view.ex:176: imported Phoenix.HTML.Form.date_input/3 conflicts with local function                   
    (elixir) src/elixir_locals.erl:89: :elixir_locals."-ensure_no_import_conflict/3-lc$^0/1-0-"/2                                             
    (elixir) src/elixir_locals.erl:89: anonymous fn/3 in :elixir_locals.ensure_no_import_conflict/3                                           
    (stdlib) erl_eval.erl:670: :erl_eval.do_apply/6                    
    (elixir) lib/kernel/parallel_compiler.ex:198: anonymous fn/4 in Kernel.ParallelCompiler.spawn_workers/6                                   
could not compile dependency :torch, "mix compile" failed. You can recompile this dependency with "mix deps.compile torch", update it with "mix deps.update torch" or clean it with "mix deps.clean torch"     

So, I renamed the private function Torch.FilterView.date_input into Torch.FilterView.torch_date_input.

This PR should resolve: #81

I have the same problem can we merge this?
