typescript from org src buffer -- tide, lsp

[Greg Minshall <minshall@umich.edu>]

hi.

i'm wondering if anyone programming in typescript might have run into,
and solved, this "problem", of tangling into a subdirectory, and tide
[1] not being able to resolve "relative" imports.

i have a file in path /a/b/foo.org.  it includes various source blocks,
and they do things like `:tangle c/d/bar.ts`.  another source block,
tangled into in c/d/fubar.ts, say, does something like:
----
import Bar from "./bar"
----

when i open an Org Src edit buffer from fubar.ts's source block, with
tide mode [1] enabled, i get a complaint
----
Cannot find module './bar' or its corresponding type declarations. [2307]
----
tide (or, really, iiuc, tsserver) appears to be, reasonably, looking for
/a/b/bar.ts, and not finding it.  but, i haven't been able to figure out
how to talk tide into looking elsewhere.

i've done things like add "rootDirs" to `tsconfig.json`, to no avail.  i
haven't been able to get lsp-mode [2] to work for this scenario, either.

anyway, in case anyone has done exactly that, i'm asking.

cheers, Greg
