Entry header `time` setter requires `Date` since v0.5.15

Prior to v0.5.15, something like this would work:

zip.getEntries()[0].header.time = "2024-01-01"

Since v0.5.15 this code gives:

Uncaught TypeError: val.getFullYear is not a function
    at Utils.fromDate2DOS (node_modules/adm-zip/util/utils.js:328:13)
    at set time [as time] (node_modules/adm-zip/headers/entryHeader.js:101:34)

I believe this is because the setter for time now requires a Date object. Is this intentional? This breaks some existing code.
