Fixes from IBOIS's dry run (#131)

* FIX: avoiding error for default drop-on-canvas component assembly

* FIX: no default canvas drop error

* FIX: canvas drop error

* ADD: CONTRIBUTING.md that had been erroneously deleted some time ago

* ADD: CONTRIBUTING.md that had been erroneously deleted some time ago [skip ci]

* FIX: canvas drop error again

* FIX: removing contributing

* FIX: to problematic none catch for canvas  drop error

* FIX: sensitivity of joint detector to planar faces in roundwood case [skip ci]

* FIX: no canvas error drop

* FIX: joint preview for single beams

* FIX: no arrow for single beam

* ADD: new mean value for the compute and viz error components and csv export

* UPDATE-FIX: assembly joint faces meshes in the same order as pc segments

* FIX: joint segmentator always looking for planar segments (not roundwood)

* FIX: segmentation returns empty segment if no corresp. seg. found

* FIX: none values for unassociated joint faces are well handled

* FIX: error estimation deals with none values in the evaluation of the etrema

* FIX: n_joint is an integer, not a list [skip ci]

* ADD: new enum to catch joint with missing points or too far

* ADD: docstrings for new enum

* FIX: typo in name

* FIX: bug for missing dataclass due to order of appearance

* WIP-UPDATE: add support for enum DFInvalidScanElement in DF_joint_segmentator

* FIX: SetUserString instead of enum use for pointcloud flags

* ADD: metadata for i_joint_displacement_tolerance parameter

* FIX: give to joint face pointclouds the same UserString as the joint they are a part of

* FIX Normal Segmentator and Colorize Cloud don't go red when dropped on canvas

* REFACTOR-FIX: added the missing clouds and too far joint detection for the computation of error

* FIX: working mesh visual for error

* FIX: adaptation for log anaylsis

* ADD: example files

* WIP: started working on tutorial docs

* FIX-WIP: temporary attempt to avoid assembly segmentator from breaking computing error comp

* WIP-FLASH: temporary save for documentation on subtractive

* FIX: face order for per-face analysis in DFCloudMeshDistance component corrected

* FIX: correct export of joint labelling

* ADD-CAP: tutorial for subtractive

* ADD-CAP: added the log section to subtractive tutorial

* FIX: preview assembly solved for logs
