Prepare v1.2.0 release

[daniel-j-h]

The last v1.1.0 release was last year in September - we should do another release.

From v1.1.0...master a release would include

• road handler
• lovasz loss
• new metrics
• fine tune and continue training
• osm data edge case fixes
• better building dataset creation from osm data
• cuda 10, pytorch 1.1

In addition good potential tickets to also include are

• Move simplification to rs merge pipeline step #16 simplification issue
• Generalizes post-processing handlers across zoom levels, closes #51 #88 generic zoom level handling
• Implements Feature Pyramid Network #75 decide on fpn
• Adds squeeze and excitation (scSE) modules, resolves #157 #161 decide on scse

And we are blocked by

• Updates readme to recommending our docker images #154 - up to date docs
• Re-enable automated docker builds #153 - automated docker image builds
• Fixes torchvision installation on travis #163 - fix travis integration

@jacquestardie I can not push tags or create a release here on Github. How do we move forward?

Hoping to have an answer to that in a few days - will update here once there's a clear path forward.

We managed to unblock all our hard requirements for this release pretty quickly. I will do a v1.2.0 release now - the fpn / scse / fpa changes are currently queued up on my rig but it takes a while to crunsh through them. Let's get this out first and then iterate on it.
