ODM 2.0 - Migration to 18.04, Python 3.6, new features, bug fixes

[pierotofy]

This is a major PR (not ready yet, opening a draft to allow early feedback/contributions) that:

• Upgrades the target OS to Ubuntu 18.04
• Upgrades Python to version 3.6
• Upgrades PDAL/Entwine to the latest release

Tentatively I will also try to upgrade OpenSfM to the newest version, which has many new speed improvements, although it's still in active development, so I might hold off on that for a bit until the codebase stabilizes.

Due to possible breaking changes for some users that run this natively (Python 2 vs Python 3 chaos), this will mark a 2.0 release. I will try my best not to break things and provide a smooth path to upgrade.

Does this warrant a quadratik fund?

[pierotofy]

No need, this is a necessary upgrade.

[pierotofy]

Should fix (or at least improve substantially) #1113 and #1090

[pierotofy]

Guarantees #1110 will never occur (I couldn't reproduce it, but should be fixed).

Closes #834

Implements #983

Whoa!

[pierotofy]

Implements #897

People can now include a geo.txt file that specifies/overrides the camera center coordinates without having to fiddle with exiftool to set GPS tags.

Format:

EPSG:<code> or <+proj definition>
image_name geo_x geo_y [geo_z] [omega (degrees)] [phi (degrees)] [kappa (degrees)] [horz accuracy (meters)] [vert accuracy (meters)]

Use via --geo <path_to_file>. Works like the --gcp option.

Image masks support for 3D:

[pierotofy]

Aaand... image masking for orthophotos:

[pierotofy]

To add a mask, simply create a new image:

<filename>_mask.JPG (make sure to match the extension, including uppercase/lowercase)

For example, DJI_0018.JPG can have a mask by creating a DJI_0018_mask.JPG file and include that in the list of images.

[Saijin-Naib]

Is it possible to use PNG, BMP, or another lossless image format for the mask?

[pierotofy]

Currently the extension must match that of the input image.

Tnx for this new feature!
Can CSV be used or only TXT?

[pierotofy]

Only TXT. But it's easy to convert from CSV.

[pierotofy]

Masks can now use arbitrary extensions (.png, .bmp, .unicorn, .whatever).

[pierotofy]

Adds the --tiles option to generate static tiles, since NodeODM will no longer be in charge of this.

Good! Tested this weekend without issue. Just forgot to update here... . Looks great, installs easily, processes fine with no noticable issues.
