Jupyter notebook display

[smesnage]

User feedback (Richard!) suggested to display the name of the FTRS file uploaded and name of the database file.
Let me know if this does not make sense, I'll explain what I meant.

Zoom! Caught me in a coding mood! Is this what you're looking for?

If so, here is the code for @bobturneruk to help me sanity-check:

# Deconvoluted Data file upload
file_upload = widgets.FileUpload(
    accept = '.txt,.ftrs', 
    description = 'Upload Deconvoluted Data',
    multiple = False,
    layout = big_button
)
file_name = widgets.Label(value="No file selected...")
def handle_file_change(file):
    file_name.value = file["new"][0]["name"]
file_upload.observe(handle_file_change, names='value')
data_uploader = widgets.HBox([file_upload, file_name])

Looks good to me, yep, this is what I meant!

Could you turn this into a PR, please, @TheLostLambda ?
