Alobugdays - 12 black square title

[eleonorefrcs]

This PR improves the black square title displayed on views.
Issue: #12

• Add parameter to activate/deactivate title (default to True)
  Test code (with add_title=False):

from aloscene import Frame
from alodataset import CocoBaseDataset

coco_dataset = CocoBaseDataset(sample=False, img_folder="test2017")
#checking if regular getitem works
stuff=coco_dataset.getitem(0)
stuff.get_view(add_title=False).render()

#check if dataloader works
for f, frames in enumerate(coco_dataset.train_loader(batch_size=2)):
    frames = Frame.batch_list(frames)
    frames.get_view().render()
    if f > 1:
        break

• Improve title rendering: Use existing put_adapative_cv2_text() to add title in Renderer class. Improve the function to adapt text size to frame size. Decrease text size if text is too long.
  Test code:

from aloscene import Frame
from alodataset import CocoBaseDataset

coco_dataset = CocoBaseDataset(sample=False, img_folder="test2017")
#checking if regular getitem works
stuff=coco_dataset.getitem(0)
stuff.get_view(add_title=True).render()

#check if dataloader works
for f, frames in enumerate(coco_dataset.train_loader(batch_size=2)):
    frames = Frame.batch_list(frames)
    frames.get_view().render()
    if f > 1:
        break
