* Use go1.14 new hash/maphash to hash both RHS and LHS instead of XOR'ing
which has been resulting in hash collisions.

* Refactor engine labelset signature generation, just use labels.Labels
instead of hashes.

* Address review comments; function comments + store result of
lhs.String+rhs.String as key.

as string in resultMetric.

* Use separate string functions that don't use strconv just for engine
maps.

* Use a byte invalid separator instead of quoting and have a buffer
attached to EvalNodeHelper instead of using a global pool in the labels
package.

* Address more review comments, labels has a function that now builds a
byte slice without turning it into a string.

* Use two different non-ascii hex codes as byte separators between labels
and between sets of labels when building bytes of a Labels struct.

* We only need the 2nd byte invalid sep. at the beginning of a
labels.Bytes
