[bug]: SayUnixTime: Sound "and" expected under digits/

[jms72]

SayUnixTime(1709043413,,HMS) fails in language German with:

-- <PJSIP/6001-0000006b> Playing 'minutes.slin16' (language 'de')
WARNING[3336698][C-00000057]: file.c:824 ast_openstream_full: File digits/and does not exist in any format

The code in main/say.c, for example line 5035 (/* Seconds */ res = wait_file(chan, ints, "digits/and", lang)) seems to expect the and sound file in sounds/digits. However, at least for en and de, and only exists in sounds directly.

It seems da, de, is, pl are affected.

Either the and sound file should be duplicated under sounds/digits, or the code should be changed to remove digits.

So if you install all of the core sounds that we provide, you end up with:

en/and
en_GB/and
es/digits/and
fr/and

So the Spanish sounds have it in the digits subdirectory, but none of the others do.
