* Whether the mapping should be high-resolution:
* - `false` (default) - lo-res mappings. Only one mapping per line, plus any locations added
* with `s.addSourcemapLocation()`. Quicker to generate and less bulky, but devtools may only
* be able to identify the correct line, not the exact column.
* - `true` - hi-res mappings. Every single character gets a mapping, so devtools can always
* pinpoint the exact location of function calls and so on.
* - `"boundary"` - semi-hi-res mappings, segmented per word boundary instead of per character.
* Suitable for string semantics that are separated by words.
* - `"experimental-range"` - hi-res mappings that use range mappings
* (https://github.com/tc39/ecma426/blob/main/proposals/range-mappings.md), a source map
* extension that can map all positions in a range with fewer mappings than mapping every
* character individually. This requires support for range mappings in the source map
* consumer, and the feature is experimental.
*
* If sourcemap locations have been specified with s.addSourceMapLocation(), they will be used here.
