freezePane(firstActiveRow, firstActiveCol) not working as expected

[gabrielwolfson]

Describe the bug
When freezing excel rows and columns, the user must either specify 'firstRow = TRUE' and 'firstCol = TRUE' or provide 'firstActiveRow' and 'firstActiveCol' arguments. When using 'firstRow = TRUE' combined with 'firstActiveCol' or 'firstActiveRow' combined with 'firstCol = TRUE', the 'firstActive_x' argument is ignored.

To Reproduce
df <- mtcars

wb <- createWorkbook()

addWorksheet(wb = wb, sheetName = "Sheet 1")

writeData(wb = wb, sheet = "Sheet 1", x = df)

###works:

#example 1: firstRow = TRUE, firstCol = TRUE
freezePane(wb = wb, sheet = "Sheet 1",
firstRow = TRUE,
firstCol = TRUE)

openXL(file = wb)

#example 2: firstActiveRow = 3, firstActiveCol = 4
freezePane(wb = wb, sheet = "Sheet 1",
firstActiveCol = 4,
firstActiveRow = 3)

openXL(file = wb)

###does not work:

#example 3: firstRow = TRUE, firstActiveCol = 4
freezePane(wb = wb, sheet = "Sheet 1",
firstRow = TRUE,
firstActiveCol = 4)

openXL(file = wb) #firstActiveCol does not freeze cols

#example 4: firstActiveRow = 3, firstCol = TRUE
freezePane(wb = wb, sheet = "Sheet 1",
firstActiveRow = 3,
firstCol = TRUE)

openXL(file = wb) #firstActiveRow does not freeze rows

Expected behavior
In example 3: first row and columns 1-3 should be frozen (only first row is frozen)
in example 4: first column and rows 1-2 should be frozen (only first column is frozen)

Example files
example_1.xlsx
example_2.xlsx
example_3.xlsx
example_4.xlsx

Additional context
Given the easy workaround, it's not critical that this be addressed on the back-end. It might be simpler to include a note in the documentation.
