added tf version to colab master notebook

[amrzv]

Hi.
Added tf version 1.13.1 (from requirements), that needed to be installed, now notebook works well.
Founded some issues, that will be resolved: #30, #26, #35

[amrzv]

Update: should be intel-tensorflow<2 works fine. See this issue: #7

[amrzv]

Now made it actually works with latest tensorflow==2.5. Allso, changes were made to submodule face_toolbox_keras
Beside of rewriting code in new tensorflow style, there were some bugs like this one:

fewshot-face-translation-GAN/networks/generator.py

Line 27 in 994a709

inp_segm_mask = Input(shape=(input_size*16, input_size*16, nc_in))

wrong mask shape:

- inp_segm_mask = Input(shape=(input_size, input_size, nc_in))
+ inp_segm_mask = Input(shape=(input_size*16, input_size*16, nc_in))

To run notebook you should open notebook from my fork and change first line:
!git clone --recursive https://github.com/shaoanlu/fewshot-face-translation-GAN.git
to
!git clone --recursive --branch tf-version-in-notebook https://github.com/amrzv/fewshot-face-translation-GAN.git

Runs without errors in default colab environment without needed installations anything.

@amrzv Amazing, I was trying by myself to get it resolved and found this after a day spent on errors.
Cheers!
