Internally, a cursor to the last accessed item is kept, to make sequential or
mostly-sequential access to items faster, but totally random access will
still be somewhat ineffecient. Accessing items near the start or end of the
subtitle file can also be done reasonable fast however.

This function uses the Aegisub SSA parser to split a string into override
blocks and text, and give separate access to each tag in override blocks.

@text (string)
The SSA-format string to parse.
Returns: A Parsed Tag Data table.

@tagdata (table)
The Parsed Tag Data table to "unparse".

Parsed Tag Data table
The Parsed Tag Data table is an Array Table containing a number of Parsed Line
Block tables.
Parsed Line Block table
A Parsed Line Block describes part of a line. (See ass_dialogue.cpp:70 for a
more complete description of this.
There are several classes of Parsed Line Block tables, which have slightly
varying fields.
Base Parsed Line Block table class
class (string)
One of:
"plain",
"override",
"drawing"
"plain" and "drawing" Parsed Line Block table classes
text (string)
The text contained in this block.
"override" Parsed Line Block table class
This class doesn't have any new, specifically named fields. It does, however,
have multiple integer indexed fields, ie. acts as an Array Table.
Each of these indexes refer to a table of type Parsed Override Tag.
Parsed Override Tag table
This table describes a single override-tag in an SSA line.
valid (boolean)
Whether this tag was parsed as a valid tag, or is just used for representing
junk in the middle of the line.
name (string)
Name of the tag, including leading backslash character. (In the case of
invalid tags, the leading backslash might not be present.)
paran (boolean)
Whether this tag has parantheses in its textual representation.
params (table)
This is an Array Table containing the parameters for this tag. It will
always have the maximum number of entries that can be supported by the tag,
but in case of omitted parameters, the parameters omitted will have 'false'
for value in this table.
