/**
 * Parse messages from a chunk of data sent by tsserver.
 *
 * Notes:
 *
 * - A 'message' takes the form:  "Content-Length: <number>\r\n\r\n<json>".
 * - A single chunk may contain multiple messages.
 * - A single chunk of data may contain an incomplete message, or contain complete message(s) followed by an incomplete one.
 *
 * Example that contains only one message:
 *
 *     "Content-Length: 238\r\n\r\n{\"seq\":0,\"type\":\"event\",\"event\":\"projectLoadingStart\",\"body\":{\"projectName\":\"/Users/ben/.srcbook/tsconfig.json\",\"reason\":\"Creating possible configured project for /Users/ben/.srcbook/srcbooks/4bs7n0hg8n0163du5ik9shjdmc/main.ts to open\"}}\n"
 *
 * Example with multiple messages:
 *
 *     "Content-Length: 609\r\n\r\n{\"seq\":0,\"type\":\"event\",\"event\":\"telemetry\",\"body\":{\"telemetryEventName\":\"projectInfo\",\"payload\":{\"projectId\":\"ebdc8edc2317622018a25bdb7fd3ef5e41538960354c166d5577561381bed531\",\"fileStats\":{\"js\":0,\"jsSize\":0,\"jsx\":0,\"jsxSize\":0,\"ts\":5,\"tsSize\":2084,\"tsx\":0,\"tsxSize\":0,\"dts\":7,\"dtsSize\":1567085,\"deferred\":0,\"deferredSize\":0},\"compilerOptions\":{},\"typeAcquisition\":{\"enable\":false,\"include\":false,\"exclude\":false},\"extends\":false,\"files\":false,\"include\":false,\"exclude\":false,\"compileOnSave\":false,\"configFileName\":\"tsconfig.json\",\"projectType\":\"configured\",\"languageServiceEnabled\":true,\"version\":\"5.5.3\"}}}\nContent-Length: 435\r\n\r\n{\"seq\":0,\"type\":\"event\",\"event\":\"configFileDiag\",\"body\":{\"triggerFile\":\"/Users/ben/.srcbook/srcbooks/4bs7n0hg8n0163du5ik9shjdmc/main.ts\",\"configFile\":\"/Users/ben/.srcbook/tsconfig.json\",\"diagnostics\":[{\"start\":{\"line\":2,\"offset\":3},\"end\":{\"line\":2,\"offset\":11},\"text\":\"'module' should be set inside the 'compilerOptions' object of the config json file\",\"code\":6258,\"category\":\"error\",\"fileName\":\"/Users/ben/.srcbook/tsconfig.json\"}]}}\nContent-Length: 76\r\n\r\n{\"seq\":0,\"type\":\"event\",\"event\":\"typingsInstallerPid\",\"body\":{\"pid\":44901}}\n"
