Fix dataformat list for protocol templates

See merge request !146

This method simplify the code to retrive the format
to put as default value when, for example, creating
a new input or output for an algorithm as well as
values for tests.

Only the setter is used, remove the unused code and
just use the setter.

The template protocols usable dataformat list does not
contain the base types.

Make new dialog comboboxes searchable

can start typing what he is looking for rather than
having to scroll a possibly long list of assets.

Fixes #227

Fix algorithm migration handling

Closes #275

See merge request !143

It ensure that the declaration loaded matches the one
from the migrated algorithm.

Legacy is used as a temporary state to people can
execute their algorithms using the V2 backend.

The editor does not allow to create legacy algorithm, therefore
this will trigger an update of the code directly to become what
is closer to v1 which is sequential.

Only the code was updated

Gracefully handle default values of plotterparameters

Closes #278

See merge request !142

logging.exception instead of logging.error

Sometimes the default value of a parameter does not have the required
type of that paramter and this can lead to failures further down the
code. Here, we're converting the default value to the required type so
that errors do not occur.
Fixes #278

Fix parameter filter crash

Closes #276

See merge request !141

If the value was not changed from the default, it won't be
dumped and thus when filtering, it won't be there.

Remove unwanted additional channel color on toolchain edition/creation

Closes #267

See merge request !139

Fixes #267

Add folding to dataformat editors

Closes #236

See merge request !140

The editor can get pretty long pretty quickly if many
fields are added. Especially array entries or object
entries. Making their repsective editors foldable
allows the user to more easily go through the content
of the editor.

Since QLineEdit has two different constructors, when
passing only a parent parameter, it must be explicitly
named.
