A positive value, in milliseconds. It is the threshold used to determine
if we should assume that the text stream actually starts at time zero.
If the first sample comes before default_text_zero_bias_ms, then the
start will be padded as the stream is assumed to start at zero. If the
first sample comes after default_text_zero_bias_ms then the start of the
stream will not be padded as we cannot assume the start time of the
stream.
This work was done over ~80 individual commits in the `cmake` branch,
which are now being merged back into `main`. As a roll-up commit, it is
too big to be reviewable, but each change was reviewed individually in
context of the `cmake` branch. After this, the `cmake` branch will be
renamed `cmake-porting-history` and preserved.

This sets the groundwork for more generic text cues by having a more
generic object for the settings and the body. This also changes the
TextSample to be immutable and accepts the fields in the constructor
instead of using setters.

Previously, the text padder media handler would assume that text always
started at time zero. This would work for VOD but would result with a
large pad at the start of LIVE content.
To avoid this, the text padder will use a bias to test whether or not it
thinks the content starts at zero. Right now the bias is set to be 10
minutes, but will later be configurable with a command line flag.
10 minutes was used as LIVE content will have much larger values and VOD
content should have much lower values.

Created a media handler to come after parsers that will handle filling
in gaps between text samples. The padder takes a min duration, and if
the samples do not cover the min duration when flushed, one last empty
sample will be injected so that the samples will go up to the min duration.
