Commit Message

Improve sorting part performance.

* Replace `dplyr::arrange()` with `data.table::setorder()` to improve performance. It improves performance by 2-4x.
* Add `data.table (>= 1.9.6)` to dependencies, as `setorder()` supports `data.frame` only since `1.9.6`.

For 10 millions records eventlog:

```R
el_10m <- generate_eventlog(10000000, 2000000, c("campaign", "sale"), c(10, 3))
system.time(create_pmap(el_10m))
```

The comparison is following:

```
           user  system elapsed
Before   68.376   0.872  69.329
After    21.983   3.982  26.823
```
