write_bin: Write data table into bin file
In dkyleward/caliperR: Interacct with Caliper Software from R

Write the data table into a TransCAD binary file (.bin) given the filename and description. If the table has column labels, those will become field descriptions.

1	write_bin(binData, binFilename, description = "", dnames = NA, n2i = TRUE)

`binData`	`data.frame` The data table to write
`binFilename`	`string` The file in which to write
`description`	`string` A description of the binData
`dnames`	`Named vector` of display names where each name is a column name and each value is the display name to use. For example: `c("hh" = "Households")` will assign the display name "Households" to column "hh".
`n2i`	`bool` Whether to try to convert numerics to integers. This leads to integer columns in the bin (instead of real), which are smaller and easier to read. Defaults to `TRUE`. Conversion does not happen if the column contains decimal values.
