将 cborg 从 6.x 升级到 7.x

### ⚠ BREAKING CHANGES

* **json:** validate numeric fractions and exponents
* **json:** cborg/json sorts map keys by UTF-8 bytes, not UTF-16 code units.
* **encode:** encoded float16 subnormals that are not powers of two (multiples of 2^-24 below 2^-14) are now a 3 byte f9 item, not 5 bytes. Anyone hashing or comparing those bytes sees different output.
* **encode:** anyone encoding boxed Number, String, Boolean or BigInt objects now gets the primitive's bytes. Before, they got an empty map or an index-keyed map (new String('a') gave {"0":"a"}).
* **decode:** the decode option strictUtf8 is removed. Callers still passing it get replacement-character decoding instead of an error. Rename it to rejectInvalidUtf8.
* **encode:** encode() of a Map whose keys encode to equal bytes, and encodeInto() with a destination that is not a Uint8Array, now throw. Both produced malformed or corrupt output before. Output from
* **encode:** type-level only. ByteWriter in cborg/interface drops chunks and requires pushArr(number[]) and pushBytes(Uint8Array). TypeScript code implementing ByteWriter or reading writer.chunks will not compile. No runtime export or encoded output changed.

### Features

* **bench:** compare base and head in separate processes and comment on PRs ([#237](https://github.com/rvagg/cborg/issues/237)) ([bc02bfd](https://github.com/rvagg/cborg/commit/bc02bfde4569bd1639ef5263e176b5215acff614))
* **cli:** annotate tags and decode CIDs in diagnostic output ([1db60bc](https://github.com/rvagg/cborg/commit/1db60bca45f78f8c951d897fea12b86c332d57cb))
* **cli:** expand tag 24 embedded CBOR in diagnostic output ([2a66a4d](https://github.com/rvagg/cborg/commit/2a66a4d3e8dfa711384b1270a6f51cf3483c4dd5))


### Bug Fixes

* **cli:** validate --width, reject lossy JSON output, drop stack traces ([#238](https://github.com/rvagg/cborg/issues/238)) ([60f70da](https://github.com/rvagg/cborg/commit/60f70da2a5afc4b80e9f70691c6bbfa14e791908))
* **decode:** reject duplicate tagged-Map keys before values ([cc8d7cb](https://github.com/rvagg/cborg/commit/cc8d7cb76f76aa27ee9c5bf793c85bd8f87f8d75))
* **decode:** rename strictUtf8 to rejectInvalidUtf8 ([#234](https://github.com/rvagg/cborg/issues/234)) ([fa82030](https://github.com/rvagg/cborg/commit/fa82030d5cabef6a730ad3e6f2c4a1273a8002f2))
* **encode:** encode all float16 subnormals as float16 ([#236](https://github.com/rvagg/cborg/issues/236)) ([3b0ad88](https://github.com/rvagg/cborg/commit/3b0ad88f028ebc8686273755524194ae101543c6))
* **encode:** reject duplicate map keys and invalid encode inputs ([#233](https://github.com/rvagg/cborg/issues/233)) ([1ca3eb7](https://github.com/rvagg/cborg/commit/1ca3eb73c933f59c7d2a60853024159abaee8695))
* **encode:** unbox Number, String, Boolean and BigInt objects ([#23
