* the `exp` parameter to `secp256k1_rangeproof_sign` is set such that
* the proven range is compressed. In particular this function will always
* overestimate the size of single-value proofs. Also, if `min_value`
* is set to 0 in the proof, the result will usually, but not always,
* be 8 bytes smaller than if a nonzero value had been passed.
*
* The goal of this function is to provide a useful upper bound for
* memory allocation or fee estimation purposes, without requiring
* too many parameters be fixed in advance.
*
* To obtain the size of largest possible proof, set `max_value` to
* `UINT64_MAX` (and `min_bits` to any valid value such as 0).
*
* In: ctx: pointer to a context object
* max_value: the maximum value that might be passed for `value` for the proof.
