从 Odoo14开始的新功能
在此之前，会计凭证的编号是取自 ir.sequence ；后面为了引入 编号重排功能，因此不再从 ir.sequence 获取编号
凭证编号以'/' 隔开分为3个部分， 第一个部分是 prefix； 第二部分是 年份； 第三部分是 凭证的顺序号
新建凭证时自动编号
- Prefix 从journal 上获取
- 年份就是 年份
- 顺序号就是 在指定journal、年份，该凭证的顺序号，从 0001 开始
重新编号
- 基于 第一个 新编号，重新编号
- 可以 使用现有的顺序；也可以按记账日期排序

[IMP] account: rework name sequences
Task 2146469
Rework the name computation:
* It doesn't use ir.sequence anymore
* It is an editable computed field
* Add a renaming tool
This allows the user to tweak the sequences more easily than having to
get through the ir.sequence settings.
The sequence depends on a parameter of the journal: continuous, montly
and yearly restart of the sequence. Everytime a new period is started,
try to make a pattern form another period.
The incrementing is done by taking the previous name, ordered
lexicographically, splitting it by taking the digits at the end, adding
1 and re contstruct with the prefix.
** This means there could be cases where the prefix has a big importance
on the next number. For instance, if you have
INVOICE/2019/0001
INVOICE/2019/0002
and then rename the last one to INV/2019/0002, don't expect the next
number to be INV/2019/0003. It will be INVOICE/2019/0002 (again) because
the highest number was INVOICE/2019/0001.
You will then end up with
INVOICE/2019/0001
INV/2019/0002
INVOICE/2019/0002
