Feature request: Support standard VTT subtitle files

[inglesuniversal]

I would be awesome if your script can support standard VTT files ... having this format as seen below ...

00:00.000 --> 00:23.600
 Even though it's been so long, my love for you keeps going strong.
00:23.600 --> 00:31.120
 I remember the things that we used to do, a kiss and the ring to the sunshine through.
00:31.120 --> 00:38.320
 I tried to deny it, but I'm still in love with you.
00:38.320 --> 00:42.160
 I miss you like crazy.
00:42.160 --> 00:46.000
 I miss you like crazy.
00:46.000 --> 00:56.720
 Ever since you waited way, every hour of every day, I miss you like crazy.
00:56.720 --> 01:00.400
 I miss you like crazy.
01:00.400 --> 01:08.480
 No matter what I say you do, there's just no getting over you.
01:08.480 --> 01:16.880
 I can see the love shining in your eyes and come to such a sweet surprise.
01:16.880 --> 01:24.240
 If scenes believing it's worth so wait, so hold me and tell me it's not too late.
01:24.240 --> 01:29.360
 We're so good together, we're starting forever now.
01:29.360 --> 01:33.440
 And I miss you like crazy.
01:33.440 --> 01:37.360
 I miss you like crazy.
01:37.360 --> 01:48.320
 Ever since you waited way, every hour of every day, I miss you like crazy.
01:48.320 --> 01:51.760
 I miss you baby.
01:51.760 --> 01:55.200
 I love like ours will never end.
01:55.200 --> 02:05.200
 Just touch me and I'll never get.
02:14.000 --> 02:21.360
 Just one line and we'll never match a feeling like we used to do.
02:21.360 --> 02:30.240
 Hold on tight and put everything on where we're going to make it through.
02:30.240 --> 02:37.600
 If scenes believing it's worth so wait, so hold me and tell me it's not too late.
02:37.600 --> 02:42.640
 We're so good together, we're starting forever now.
02:42.640 --> 02:46.800
 And I miss you like crazy.
02:46.800 --> 02:51.440
 I miss you like crazy.
02:51.440 --> 02:57.440
 No matter what I say you, there's just no getting over you.
02:57.440 --> 03:01.760
 And I miss you baby.
03:01.760 --> 03:05.360
 All the time you don't love your baby.
03:05.360 --> 03:10.800
 When a feeling gets this start, you know the real thing.
03:10.800 --> 03:20.640
 Come along and I'll miss you.
03:20.640 --> 03:23.680
 I miss you like crazy baby.
03:23.680 --> 03:30.800
 All the young sweet love is the same thing.
03:30.800 --> 03:34.480
 I miss you like crazy.
03:34.480 --> 03:41.920
 I love like ours will never end.
03:41.920 --> 03:44.480
 Just touch me and I'll never get.
03:44.480 --> 03:50.720
 Just one line and we'll never match a feeling like we used to do.
03:50.720 --> 04:06.960
 Just one line and we'll never match a feeling like we used to do.
