* Add Reader/ReadBytes fuzz tests and limits

* Fix crash in ReadTimeBytes
* Limit map/array size on ReadIntfBytes
* Expose `SetMaxRecursionDepth/GetMaxRecursionDepth` to manage max recursion depth.
* Expose `SetMaxElements/GetMaxElements` to limit array, bin, map and extension sizes.
* Expose `SetMaxStringLength/GetMaxStringLength` to limit string/map key sizes.

All of these will allow stricter control over decoding memory usage.

Bumps minimum version to Go 1.22

* Upgrade linter, fix issues reported.
* Upgrade tinygo and ci-linter install version
* Add corpus

…ew directive:vartuple) (#399)

* Decode/Unmarshal a msgpack array of arbitrary length into a struct (new directive:vartuple)

* Allows for binary map keys
* Allows for non-string map keys to be shimmed as well as cast from string type aliases.
* Allows automatic conversion of some map key types to/from string.

Adds directive `maps`

* `//msgp:maps binkeys|shim|autoshim`

Not adding the directive will retain current behaviour where maps without string keys are ignored.

Adding `binkeys` will allow for binary marshaling of map keys. Types are inferred with standard rules. Binary encoding can be shimmed and can return any standard type. See `_generated/map_bin_key.go` for examples.

Adding `shim` will require you to add shims to custom map key types. Shims must be with string type. See `_generated/map_shim_key.go` for examples.

Adding `autoshim` will add automatic shimming to map keys that are `uint, uint8, uint16, uint32, uint64, int, int8, int16, int32, int64, bool, float32, float64, byte` - so these are written as a string. Standard `strconv.Parse/Format` functions are used. Aliased types are not supported, but `msgp:replace MyInt with:int` directive can be used and this will be picked up.

Adds `witherr:true|false` to `//msgp:shim` directives, so shim de-serializing can return errors.

Updates/Resolves: #331 #345 #305 #257 #232

Quirks:

* Sizing is not perfect and can sometimes be collapsed from a range to constant.
* These maps are not currently readable by "Interface" functions.

Make it possible to add directives as commandline parameter.

Alternatively to `//msgp:tag json` directives can also be specified using the `-d` flag. Example: `msgp -d "tag json"`. Multiple flags can be added.

Directives in files take precedence over commandline.

Bonus: Print info on all directives.
