+Subject: fix: remove unused llhttp variables
+
+Node.js updated llhttps in https://github.com/nodejs/node/pull/30553,
+which updated some of the llparse_blobs. To keep numbering consistency,
+it left the newly unused ones, which causes compilation failures in Electron
+as we do not allow unused variables.
+
+Fixed in https://github.com/nodejs/llparse/pull/34; this patch can be removed
+as soon as llparse v6.2.1 is rolled into Node.js
