v0.15.2

• Fixed. Whether the number branch of a oneOf admits an integer was
  judged by a copy of the contract's old float multipleOf rule; with
  0.12.1 the contract judges on the decimals and the two disagreed on 4670
  of the integers in ±100000 for multipleOf: 0.7 — the generator kept
  58254 on the integer branch, the contract saw it on both, and a case
  called valid was rejected. The verdict is the contract's now:
  SchemaCheck::isMultipleOf() (openapi-contract 0.12.2, required as
  ^0.12.2). The zoo's amounts.create carries step (0.7 beside a wide
  integer branch) and the contract's corpus is re-recorded (#132).
• Fixed. A number schema whose bound is so wide that its decimal
  multiples need more significant digits than a double holds
  (|bound| × 10^decimals > 2^53) fails closed at compile time instead of
  rounding onto a neighbouring decimal that is no multiple; a multiple that
  divides one (1, 0.5, 0.25) is exempt, every double that wide being
  an integer. A property pins that every generated multiple is one to the
  contract (#133).
• CI. static-analysis.yml runs composer rector on every PR: 0.15.0
  shipped with a rule red in a test its last commit added, and nothing
  before the next PR ran rector.
