Transposes a list of list, and turns it inside out, similar to the
function transpose() in package purrr.
Examples
x = list(list(a = 2, b = 3), list(a = 5, b = 10))
str(x)
#> List of 2
#> $ :List of 2
#> ..$ a: num 2
#> ..$ b: num 3
#> $ :List of 2
#> ..$ a: num 5
#> ..$ b: num 10
str(transpose_list(x))
#> List of 2
#> $ a:List of 2
#> ..$ : num 2
#> ..$ : num 5
#> $ b:List of 2
#> ..$ : num 3
#> ..$ : num 10
