Added newly published paper.

# spaSim 1.2.0

Development version in Bioconductor 3.18.

# spaSim 1.1.2

BUG FIXES

* Fixed documentation of argument `jitter` in `TIS()` and `simulate_background_cells()`.
* Fixed incorrectly plotted image in README.

# spaSim 1.1.1

SIGIFICANT USER CHANGE

* `simulate_background_cells()` added an option (`method = "Even"`) to simulate
evenly spaced background images. This change is accompanied with addition of two 
parameters, `method` - to choose the background cell distribution and `jitter`
- the parameter to simulate evenly spaced background cells. Tutorials and 
function `TIS()` were modified accordingly.
