For a tibble dataset with a `cell`

and `value`

columns, it sums up all values per cell (total library size), and scales
the value for `10^x`

where `x`

is the median nuimber of digits
in each total value size.

For instance for numbers of the order of ~1000 it will rescale the library
size by a factor 1000, taking all values around ~1.

`auto_normalisation_factor(x)`

## Arguments

- x
A tibble with a `cell`

and `value`

columns.

## Value

A tibble, aggregated by cell with total values (sum), rescaled
by the estimated constant.

## Examples

```
data('example_input')
example_input$x_rna %>% auto_normalisation_factor
#> NULL
```
